Consider the block diagram attached, describing a process under Proportional-Integral-Derivative control. 1) Is the system open loop stable? Justify your answer 2) Let Ki = 10. Use the Routh-Hurwitz criterion to find the range of Kd, and Kp in terms of Kd, so that closed loop stability is achieved. 3) Suppose that Ki = 10, Kd = 1, and Kp = 15. A Bode plot of the open loop transfer function with these parameter values is shown in the attachment. Sketch a Nyquist plot for this system and use this sketch to determine if the system is closed loop stable.

Consider the block diagram in the attached figure Q3.1, describing the process under Proportional-Rate Feedback control. 1) Find a closed loop system transfer function in terms of controller gains, Kp, Kd. 2) Find the value gains Kp,Kd such that the resulting Percent Overshoot of the closed loop step response will be equal to 20% and the settling time, T[settle 2%], will be equal to 1 second. Write the closed loop transfer function expression for the computed values of the controller gains. For the computed values of the controller gains, find the closed loop system DC gain, Kdc, and the closed loop steady state error for the step response, e[#%]. 3) The attached figure Q3.2 shows the sys... click for more
