PYKC 8-Feb-11 E2. This paper presents a fixed-order H ∞ controller design based on linear matrix inequalities for multi-input-multi-output systems. Circuits that include an inductor, capacitor, and resistor connected in series or in parallel are second-order circuits. But in physical systems the order of N(s) should always be smaller than the order of D(s). If the output of control system for an input varies with respect to time, then it is called the time response of the control system. A system is able to change in two ways: (1) Individual parameters change in a continuous manner but the structure of the system does not alter; this is known as "first-order change. Part II: An example of a third order system, 8. So, we have to convert the non-unity feedback system into unity feedback system. The initial conditions for x.

Because the elimination of variables is not an inherent part of this process, state models can be easier to obtain. Because the system has no poles or zeros at the origin, the low-frequency asymptote is constant. Second-order systems are commonly encountered in practice, and are the simplest type of dynamic system to exhibit oscillations. N(s) nominator is not important in determination of the order and type of the system. 3rd order low pass filter The company that changed the world of video games with touch-screen gaming in 2004 and motion-controlled gaming in 2006 now pioneers the next dimensional shift. Green and Limebeer: Linear Robust Control 2. For example, employers may monitor calls with clients or customers for reasons of quality control. The moti vation for this w ork is the fact that when design-ers are faced with a control engineering problem and w ant to formulate it in the optimal control frame w ork, the choice. Associated to a third order determinant there will be a 3×3 matrix: Again we write the entries of a between bars to point out this is a determinant, not a matrix! And how do we calculate the value of a 3 rd order determinant? We select, for example, the first row of D. Our contribution in ISSAC'2007: An efficient algorithm (does not require solving systems of non-linear equations). 1 Taylor methods 68 5. Unlike those at the Third Order, though, Fourth Order adults don’t feel torn apart by the conflicts of those around them because they have their own system with which to make decisions. JEL: C10, C32, C51, C53, C58 1 Introduction The dynamic state-space model was developed in the control systems literature, where physi-cal systems are described mathematically as sets of inputs, outputs, and state variables, related by difference equations. course on control theory, a sharp distinction is made be-tween closed-loop and open-loop control. tional control system design.

Compare the time and frequency responses of the true delay and its approximation. 2 Linear SISO Control Systems General form of a linear SISO control system: this is a underdetermined higher order differential equation the function must be specified for this ODE to admit a well defined solution. All modes are unstable and uncontrollable on their own, but the system stable is controllable via switching. 3 rd order Determinants: Let’s move up to third order determinants. In the case of a second order polynomial, we see that Routh’s stability criterion reduces to the condition that all a i be positive. Find the set of differential equations describing the system. Higher Order Systems In this section we shall present a transient-response analysis of higher-order systems in general terms. The PLL is a control system allowing one oscillator to track with another. First-order neuron cell bodies reside in the dorsal horn of the spinal cord. CLTF representation: (The coe cients the same as Example 2. However, there isn't any way to compensate or adjust in real systems. We can find the steady state errors only for the unity feedback systems. When the variable is time, they are also called time-invariant systems. We explore the control of third order aberrations (spherical aberration, coma, astigmatism, and Petzval field curvature) through wavefront coding. 0) Imports graphics, grDevices, stats Description Functions for statistical analysis, prediction and control of time. Many practical systems are first order; for example, the mass-damper system and the mass heating system are both first order systems. damp(sys) displays the damping ratio, natural frequency, and time constant of the poles of the linear model sys. 'I see that the cat is black'). In particular given that the AR(2) test in your example does not reject the null hypothesis of no second-order serial correlation, the second lagged level of the dependent variable would qualify as a valid instrument and it is typically a stronger instrument that just the 3rd or 4th lag. Build order tickets by offering a multi-meal discount -- for example: place a second or third-order at the same time and receive 5% and 10% off respectively. This example considers the design of a second-order system that will satisfy certain time-domain specifications. In other words it relates to a 2nd order transfer function and not a 4th order system. Example 2 (Cruise Control). The influence of Feedback. Express t in the system time units, specified in the TimeUnit property of sys. 6 Analysis & Design-RF and Digital Systems Using System Design THD Total Harmonic Distortion TOI Third-Order Intercept Point (also IP3) UMTS Universal Mobile Telecommunication System VCO Voltage-Controlled Oscillator VSWR Voltage Standing Wave Ratio XP X-Parameters*. 3 A first-order system response 8.

With the unsurpassed flexibility provided by a Data Acquisition Processor-based system, and with the control capabilities provided by the PID command of DAPL, there is no longer any reason to settle for control systems with lesser capability. This New World Order is theorized by some to involve a group or groups of elitist people bent on ruling the world through a single worldwide system of government. The cost is quadratic. INTRODUCTION Control systems with time-delay play an important role. Third Order Control System. cal motion control systems. The Bode angle plot always starts off at 00 for a second order system, crosses at —90' and asymptotically approaches —1800. In the case of a second order polynomial, we see that Routh's stability criterion reduces to the condition that all a i be positive. com & [email protected] Internal Control Systems : NGC Regulation 6. t r rise time: time to rise from 0 to 100% of c( t p peak time: time required to reach the first peak. • Parts of robust control books are used instead 1. The goal is to create a control loop, something like this: In this system, the output, Y(s), is a position (correct me if i am wrong). Second-order neuron Interneuron Synapse with third-order neuron Examples Posterior (dorsal) column Medulla to thalamus (decussates in medulla) Spinothalamic tract Spinal cord to thalamus (decussates in spinal cord). In general for a particular third system of pulley having n number of pulleys, VR = 2n – 1. The general equation for Laplace transforms of derivatives From Examples 3 and 4 it can be seen that if the initial conditions are zero, then taking a derivative in the time domain is equivalent to multiplying by in the Laplace domain. Some control system design techniques require a rational transfer function; the Padé approximation for dead time is often used in this case. Typically, third- and fourth-order impacts are sufficient to explore all of the significant impacts of the initial event. Examples are given of the application of second order Cybernetics concepts in practice in studies of, and applications in, communication, society, learning and cognition, math and computation, management, and design. And if you can show the third derivative Is negative definite for all the states you care about here. Compare the time and frequency responses of the true delay and its approximation. Answer: The New World Order is a conspiracy theory which posits a new period of history bringing about a major change in the world with the balance of world power. Lawrence D. If there is no existing control within or near the project area, the Geodetic Survey Unit establishes control using GPS. Runge-Kutta 4—A solver of fourth order. Check the three conditions Q(l) > O, > O, and laol < an, which requires. The second half of the book presents material that is often considered to be from the field of "classical control. In this example, the external STB TV Input is provided by a third party. ME 413 Systems Dynamics & Control Chapter 10: Time-Domain Analysis and Design of Control Systems 9/11 Example 5 Use block diagram algebra to solve the previous example. A Bode plot maps the frequency response of the system through two graphs – the Bode magnitude plot (expressing the magnitude in decibels) and the Bode phase plot (expressing the phase shift in degrees). This way, we can advance in pseudo time with a large O(h) time step (not O(h^2)), and compute the solution gradient with the equal order of accuracy on irregular grids. Control Laboratory 3. the 4 with we will use a gain block as shown in the figure below,. Includes a payment/aging summary for all orders or for individual vendors. That is why the above transfer function is of a second order, and the system is said to be the second order system. For example, the first-order consequences of exercise (pain and time spent) are commonly considered undesirable, while the second-order consequences (better health and more attractive appearance) are desirable. enacted their order s and the later statewide order, to disentangle the effects of each. However, the third order model performs almost equally well and may be a better choice.

ECE 680 Modern Automatic Control Routh’s Stability Criterion June 13, 2007 3 where the coefficient a 1 is the result of multiplying a 1 by a 2 and subtracting a 0(0) then dividing the result by a 2. Regardless of their property and wealth, members of the Third Estate were subject to inequitable taxation and were politically disregarded by the Ancien Régime. 02 ≅ = ≅ − <. 24: Consider now the following system, obtained from the one in the previous example by adding a pole, that is The contour in the -plane is the same as in the previous example. Select the true statement regarding first-order neurons. The dominant pole approximation is a method for approximating a (more complicated) high order system with a (simpler) system of lower order if the location of the real part of some of the system poles are sufficiently close to the origin compared to the other poles. The open loop transfer function for a first order lag is: It has one real pole. The order of a control system is determined by the power of 's' in the denominator of its transfer function. The second figure denotes a two rotor system whose motion can be specified in terms of θ1 and θ2. The third-order neuron projects to the primary sensory cortex. The order of a control system is determined by the power of ‘s’ in the denominator of its transfer function. International Journal of Control: Vol. For such systems (no derivatives of the input) we can choose as our n state variables the variable y and its first n-1 derivatives (in this case the first two derivatives). Starting at the “base” of element 2, we go up by v2. Notice that most physical systems that would be intuitive for you are inherently stable. A system responds to various perturbances in a manner that is consistent with its structure, therefore, all systems do what they do and cannot be seen as pathological unless we call it that (Becvar & Becvar, 2006). How to draw a Bode plot on semi-log graph paper Question: A unity control feedback system has G(s) =80/s(s+2)(s+20). In the above transfer function, the power of 's' is two in the denominator. = + The gain parameter K can be varied.

The influence of Feedback. 4 Application-SpringMassSystems(Unforced and frictionless systems) Second order differential equations arise naturally when the second derivative of a quantity is known. Our system is Stable or not? Now to get our answer of all question of time domain specifications of in control system, we should go with the step response of a typical under damped second order system is plotted in below. Geodetic leveling is used to extend vertical control. For future works the method can be extended for analyzing of third order dynamical systems. Before, for our second-order differential equation, the only dangers in choosing large gains were due to practical considerations, like actuator limits, unmodeled dynamics, and finite servo frequencies. 8: Second-order Systems 11. In an example of linearized channel flow, we found that the most effective model reduction technique based solely on data (i. by control methods and the above are examples of what automatic control systems are designed to do, without human intervention. The true system has 4 poles (two in the process and two in the noise process) so this is expected. third order), the area downstream of the junction will retain the higher number (i. After research, when the results are discussed and assessed by a group of peers, this is the area that stimulates the most heated debate. The system shown in Fig. Problem Q3. Institute for Dynamic Systems and Control D-MAVT ETH Zur¨ ich November 17, 2017 then we know that in order for the closed-loop to be stable the Nyquist plot of L(s) should NOT encircle the 1 point. Proposed Floridan Aquifer production wells requested under this application have already been characterized in the existing CUP. Any help is really gratefully received. Sampled-data design. But in physical systems the order of N(s) should always be smaller than the order of D(s). Here, stochastic asymptotic stability (SAS) of the zero solution of a stochastic delay differential equation (SDDE) of third order such as x (t) + f(ẋ(t))ẍ(t) + g(ẋ(t− τ)) + h(x(t− τ)) + σx(t)ω̇(t) = 0 is discussed. In control engineering and control theory the transfer function of a system is a very common concept. After research, when the results are discussed and assessed by a group of peers, this is the area that stimulates the most heated debate. A cruise control system for the car would work as follows. This way, we can advance in pseudo time with a large O(h) time step (not O(h^2)), and compute the solution gradient with the equal order of accuracy on irregular grids. Let us consider first the general equation of a system ef"+ a2e" + a1e' + a0e = b2u" + blu' + bou (9) This system has poles and zeroes. By the end of this tutorial, the reader should know:. Standards shown are minimum standards for each order. Includes a Report Writing checklist for use by students. While some of these no doubt ultimately reach the thalamus by reticulothalamic projections, the principal fate and function of these collaterals is largely unknown. The first three examples illustrate the difference between RTL FSMD model (Finite State Machine with Datapath buildin) and RTL FSM + DataPath model. control system. To facilitate app access, modern, more secure apps use OAuth 2. We can find the steady state errors only for the unity feedback systems. roots, in which case the step response will be approximated by a 2nd Order Systems without nite zeros. first order) joins a higher order stream (e. Lever is one of the most commonly used simple tool that produces mechanical advantage. In general for a particular third system of pulley having n number of pulleys, VR = 2n – 1. In third-order leveling, the closure is usually made on surveys of higher accuracy without doubling back to the benchmark at the original starting point of the level circuit. The cost is quadratic. The following gure represents the system used for controlling the robotic manipulator of a Mars Rover.

The datapath consists of storage units such as registers and memories, and combinational units. These reduced-order, modified quasilinear Gaussian (ROMQG) algorithms apply to turbulent dynamical systems in which there is significant linear instability or linear nonnormal dynamics in the unperturbed system and energy-conserving nonlinear interactions. Compared to a single higher-order polynomial. Order effects refer to differences in research participants’ responses that result from the order (e. This distinction is drawn between control laws that involve references to the state of the system and control laws that are specified only in terms of time. 9 The Third-order System - X + 12 D2 13 U Is Composed Of The Second-order System Of The Previous Example With An Additional Integrator At The Input Side. Applying Routh-Hurwitz criteria to (10), it can be concluded that, given all positive PID gains, the feedback system is stable if. We demonstrate control of wireless power transfer to an implanted bioelectronic device using harmonic feedback from the backscattered field. First order changes have extended to.

Similarly, food that tastes good is often bad for you and vice versa. third party: A generic legal term for any individual who does not have a direct connection with a legal transaction but who might be affected by it. Linear Closed-Loop Control Systems: Control system, closed-loop transfer functions. Example: A State-Space Controller for DC Motor Position Control The electric circuit of the armature and the free body diagram of the rotor are shown in the following figure: For this example, we will assume the following values for the physical parameters. There are two key measurements in determining power amplifier quality, efficiency, and linearity: the third-order intercept (abbreviated TOI or IP3) point and the 1-dB compression (P1dB) point. 3-5 Traf c engineering 8. In general each example has five sections: 1) A definition of the loop gain, 2) A Nyquist plot made by the NyquistGui program, 3) a Nyquist plot made by Matlab, 4) A discussion of the plots and system stability, and 5) a video of the. which is relative order one. First order systems with PID With PID control, the closed loop transfer function of a first order system is Eq. The feedback command in MATLAB takes plant and output sensor transfer functions (G and H in the Nise book's paradigm) and produces the overall transfer function assuming negative feedback. Associated to a third order determinant there will be a 3×3 matrix: Again we write the entries of a between bars to point out this is a determinant, not a matrix! And how do we calculate the value of a 3 rd order determinant? We select, for example, the first row of D. ii The political system manipulates the economy to generate rents that bind the interests of economic actors to support the current political system. Example Consider the third order transfer function given by G(z) = z (z 0:1)(z 0:2)(z 0:9) (39) By keeping the dominant pole only, we get the first order system given by G 1(z) = z z 0:9 (40) By keeping two dominant poles, we get the second order system given by G 2(z) = z (z 0:2)(z 0:9) (41) The step response of the three systems is shown in figure 3. This is a block diagram of a third-order noise shaper, circuit located inside of a compact disc player. Part II: An example of a third order system, 8. Steady state occurs after the system becomes settled and at the steady system starts working normally. Variable Structure Control of a Hand-Launched Glider Mark R.

The datapath consists of storage units such as registers and memories, and combinational units. Includes a Report Writing checklist for use by students. Assess appropriateness of existing control environment (control design) 4. Here, sys is a dynamic system representation of the exact time delay of 0. Knee jerk reflex is a classic example of this pathway. Third-order neurons project from the VPL to areas 3, 1, and 2 of the cerebral cortex. Pole introduced. As practical, the elevations should be tied to an NGS or USC&GS NAVD 1988 datum benchmark to achieve a more-reliable source of elevations. General Overview of the Endocrine System third order — neurohormone is a releasing factor for an releasing factor for an effector hormone. The characteristic polynomial of this system is which reduces to. This paper presents an extension of the recent method to optimal control of a third order nonlinear system. control system. While First Order models are easy to compute and offer robust control, they aren't as precise as their higher order counterparts. In Chapter 2 we first provide a tutorial introduction to fuzzy control via a two-input, one-output fuzzy control design example. If the power of s in the denominator of the transfer function of a control system is 2, then the system is said to be second order control system. Check the three conditions Q(l) > O, > O, and laol < an, which requires. With one of the examples loaded in the Transport Control, press play. The order of D(s) is also the order of T. COVID-19 Resources; What We Believe; How We Serve. For the third order interactions, only those that involve treatment assignment (‘V23152’) are included. Build order tickets by offering a multi-meal discount -- for example: place a second or third-order at the same time and receive 5% and 10% off respectively. This shows that you can manoeuver your car into any parking lot by applying controls corresponding to the ‘Slide’ direction, i. Many laws in physics, where the independent variable is usually assumed to be time, are expressed as autonomous systems because it is assumed. Its early implementation was in pneumatic devices, followed by vacuum and solid state analog electronics, before arriving at today's digital implementation of microprocessors. Runge-Kutta 4th Order Method for Ordinary Differential Equations. All we're going to do here is work a quick example using Laplace transforms for a 3 rd order differential equation so we can say that we worked at least one problem for a differential equation whose order was larger than 2. And while health systems need access to medical data, including a patient’s COVID-19 test status, they don’t need access to location data. of Runge–Kutta 2nd/3rd-order and Runge–Kutta 4th/5th-order, respectively. Introduction to a 3 0 cybernetics. This domain is for use in illustrative examples in documents. With one of the examples loaded in the Transport Control, press play. These were preceded by older standards of first, second, and third order that then became subsumed under the group C in the newer scheme. Network Geometry _____ Order First First Second Second Third. Define the problem. You will design a PI controller for a DC motor using second order system formula for percent overshoot and settling time speciflcations. Some control system design techniques require a rational transfer function; the Padé approximation for dead time is often used in this case. When a cruise control. In control engineering, a state-space representation is a mathematical model of a physical system as a set of input, output and state variables related by first-order differential equations or difference equations. Consider the following block diagram of closed loop control system, which is having nonunity negative feedback. For second- and third-order approximations, we derive the statistical properties of this system and provide closed-form expressions for –rst and second unconditional moments and impulse response functions. 3rd IFAC Conference on Advances in Proportional-Integral-Derivative Control May 9-11, 2018, Ghent, Belgium Program at a Glance Wednesday Thursday Friday Author Index Keyword Index My Program PID 2018 App. E5 – Step 2.

Next, we explain what this book is about via a simple motivating example. Second Order Systems: Examples Example 1. A task analysis defines a job in terms of KSA necessary to perform daily tasks. By using this website, you agree to our Cookie Policy. Second-Order Systems. In section 3, we present new model reduction methods based on balanced truncation and modal approximation. This analysis can only be applied when. The reference system has evolved from the original 11 local markers to more than 250,000 monuments around the country. 1 Traverse Style Base Control. We can find the steady state errors only for the unity feedback systems. In this chapter a short review is given as an introduction to a stan-dardized approach to third and fourth order feedforward calculations. " (2) The system changes qualitatively and in a discontinuous manner; this is known as "second-order change. COVID-19 Resources; What We Believe; How We Serve. This definition asserts that the dynamic behavior of a state-determined system is completely characterized by the response of the set of n variables xi(t), where the number n is defined to be the order of the system. For the underdamped case, percent overshoot is defined as percent overshoot. Higher order systems can often be approximated as first order systems to a reasonable degree of accuracy if they have a dominant first order mode. How to get the state-space model of a dynamic system State-space system representation lays the foundations for modern control theory. It solves many of the limitations of the classical control theory in which transfer functions were used to asses the behavior of a closed loop system. Peet Lecture 10: Control Systems 23 / 28. 1 The compressible Euler equations in Lagrangian formulation The Euler equations for unsteady compressible flow in the reference frame of a moving control volume can be expressed in integral form in the Cartesian coordinates as d dt! Ω(t) UdΩ+! Γ(t) FdΓ= 0 (2. ("FCPA"), was enacted for the purpose of making it unlawful for certain classes of persons and entities to make payments to foreign government officials to assist in obtaining or retaining business. This shows that you can manoeuver your car into any parking lot by applying controls corresponding to the ‘Slide’ direction, i. The system whose input-output equation is a first order differential equation is called first order system. A three element vibration isolator that I have mentioned is not a 2nd order but is a 3rd order system. You would probably have some luck searching for third order transfer functions for control systems. , to do his work, to sell his goods, to manage his business. setoptions (h,p); % Apply options to the plot. We will discuss both with examples. Signs of blast lung are usually present at the time of initial evaluation, but they have been reported as late as 48 hours after the explosion. We'll use a third order equation, thought it generalizes to n th order in the obvious way. For second- and third-order approximations, we derive the statistical properties of this system and provide closed-form expressions for –rst and second unconditional moments and impulse response functions. , third order, fifth order, etc. Engineering Sciences 22 — Systems Electrical Modeling Page 4 Now we “turn on the power” and use the third dimension to indicate voltage. Validate existing controls to assess control operating effectiveness. The idea is that time is somehow is readily available to the controller, independent of the. A traverse style control system is a control scheme that traverses between two terminal points. Systems controlled using an integral action controller are almost always at least third-order. By Vicky Osterweil. The moti vation for this w ork is the fact that when design-ers are faced with a control engineering problem and w ant to formulate it in the optimal control frame w ork, the choice. 001 x km First order Major levelling control 0. The hybrid computer system emerged because the potentials of separate analog and digital computers, taken separately, proved to be inadequate when solving many new problems involving the control of moving objects, the optimization and simulation of control systems, and the development of complex training simulators. The ascending tracts of the spinal cord are quite an advanced neuroanatomy topic. u(t) FIGURE P2. In order to design a harmonic filter, information about the local power system, including environmental data, is required. But instead of simply writing y ″ as w ′, the trick here is to express y ″ in terms of a first derivative with respect to y. Here, sys is a dynamic system representation of the exact time delay of 0. Compared to a single higher-order polynomial. Technical Article An Introduction to Control Systems: Designing a PID Controller Using MATLAB's SISO Tool August 19, 2015 by Adolfo Martinez Control systems engineering requires knowledge of at least two basic components of a system: the plant, which describes the mathematically described behavior of your system, and the output, which is the goal you are trying to reach. Consider the following block diagram of closed loop control system, which is having nonunity negative feedback. s^n, type n) in D(s) gives the type of the system. Its purpose is to force the VCO to replicate and track the frequency and phase at the input when in lock. It’s no secret that setting up a simple-to-manage smart lighting control system. Note that in both pathways the second-order neuron has its cell body in the central nervous system (CNS) and gives rise to an axon that crosses the midline and ascends to the thalamus. The accurate definition of the problem affects all the steps that follow; if the problem is inaccurately defined, every step in the decision‐making process will be based on an incorrect starting point. By way of several examples, this presentation discusses the complex behavior that is revealed upon deeper investigation in to the control loop response. Let us consider first the general equation of a system ef"+ a2e" + a1e' + a0e = b2u" + blu' + bou (9) This system has poles and zeroes. The equation (7), (8) and (9) shows that the third harmonics in the three phase voltage have the same phase. The system can be represented by the following block diagram: Example 1. Example: A State-Space Controller for DC Motor Position Control The electric circuit of the armature and the free body diagram of the rotor are shown in the following figure: For this example, we will assume the following values for the physical parameters. The first coordinate reference system was established from geodetic surveys performed in 1816 and 1817. As we know, in control systems the timely behaviour is much more important than the properties in the frequency domain. This section provides an introduction to control system design methods. There really isn't all that much to this section. Control system synthesis and analysis by approximation to third-order systems. Becoming familiar with this format is useful because: 1. David Corrigan Electronic and Electrical Engineering [email protected] That is why the above transfer function is of a second order, and the system is said to be the second order system. Examples ----- The following examples are included with the code: 1. First order system is often a good mathematical model to represent the behavior of many real-world systems. Part 1: Optimized Sigma-Delta Modulated Current Measurement for Motor Control by Jens Sorensen , Dara O’Sullivan , and Shane O’Meara Download PDF Isolated sigma-delta (Σ-Δ)-based analog-to-digital converters (ADCs) have become the preferred method for phase current measurement in high performance motor and servo drives. A cruise control system for the car would work as follows. the system transient response remains the same and the effect due to the PI controller is to increase the type of the control system by one, which produces improved steady state errors. control system. Smaller non-zero pole of basic third order system of type 1. It includes financial systems for performance for stochastic dominance, the location of a bouncing robot, and road. 2 Transfer Function to State Space Conversion Consider the transfer function of a third-order system where the numerator degree is lower than. 1 First-Order Equations with Anonymous Functions Example 2. 3: Simulation diagrams for Example B. 'I see that the cat is black'). Second Order Passive Low Pass Filter. A framework for low-order predictive statistical modeling and uncertainty quantification in turbulent dynamical systems is developed here. Since that TV Input can’t directly access the HDMI video feed coming in, it must go through the TV Input Manager and use the HDMI TV Input provided by the device manufacture. 2 Runge–Kutta. We investigate consensus problem for third-order multiagent dynamical systems in directed graph. Formally, it was developed by an IT specialist. With the controller transfer function described by (5), the closed-loop system is now of third order. In general each example has five sections: 1) A definition of the loop gain, 2) A Nyquist plot made by the NyquistGui program, 3) a Nyquist plot made by Matlab, 4) A discussion of the plots and system stability, and 5) a video of the.
