Ex. 830. Design a proportional controller (Kp) cascaded with the plant: (s+10)/( (s+ 3) (s+ 9) (s+14) ) within a unity feedback system so that the dominant poles result in a 32% 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

1. Given the following unity feedback system where s+z s2 (s + 10) and the controller is a proportional controller Ge = K, do the following: a. If z = 2, find K so that the damped frequency of the oscillation of the transient response is 5 rad/s. b. The system is to be redesigned by changing the values of z and K. If the new...

QUICK UPVOTE:
As a control system engineer you have been asked to design a controller that would improve the error and the transient response for the unity feedback system below. The proposed solution must be cost-effective, so consider a passive network-based compensator. The transient response of the closed-loop transfer function to a ramp input has a 30% overshoot (%OS = 30) and a settling time Ts= 2.73 seconds. You need to decrease the peak time by a factor of 2,...
