Question:
Consider the system of Fig. P8.2-2 with .
(a) Show that the pulse transfer function of the plant is given by(b) The frequency response for is given in Table P8.2-2. From this frequency response, sketch the Bode and the Nyquist diagrams for the uncompensated system, indicating the gain and phase margins.
(c) Calculate the value of It is not necessary to find to calculate this value.
(d) Use the results of part (b) to estimate the overshoot in the unit-step response.
(e) Based on the results in part (d), are the zeros of the uncompensated system characteristic equation real or complex? Why?
(f) Use MATLAB to find the rise time . The step response will show a 21 percent overshoot.
