Ex. 830. Design a proportional controller (Kp) cascaded with the plant: (s+12)/( (s+ 3) (s+ 7) (s+15) ) within a unity feedback system so that the dominant poles result in a 36% overshoot step response. Find Kp, zeta, wn, wd, Ts, Tp, the error constant (Kp_error) and corresponding SS error. Note: Kp_error is different from Kp in the PID-TF. ans:8
