Question

The unity feedback control system is represented in Figure 3. In order to improve the performance, a PD controller is introduced in the forward path in series with the plant as shown in Figure 4.
(i). Evaluate the damping ratio, un-damped natural frequency and percentage overshoot without introducing controller.

E = 1070

(ii). Estimate the value of K_d, if the damping ratio to be improved by 25% and thus compare the change in percentage overshoot.
