Consider a state-feedback control system of the form x = Ax + Bu u = Fx where F is the 1 x 2 matrix F = [fi f2)-

QUESTION 3 Consider a unity negative feedback control system. Assume that the plant G(s) does not have an integrator and you are using a proportional compensator K. You want to increase the closed-loop step tracking performance. Currently, the steady- state tracking error of the closed-loop system with K=K_old to a unit step signal is 0.1. You would like this error to be reduced to 0.02 with a new proportional compensator K=K_new. How does the proportional gain have to change to make this possible? We assume that the closed-loop is stable for all values of the proportional gain. Do not guess as incorrect answers will incur a penalty. K_new = 6.33 K_old K_new = 5.44 K_old K_new = 5 K_old K_new = 4.66 K_old

Given the DC motor model Design a feedback control system which results in a closed loop response with a 15% overshoot and a 2% settling time of 0.5 seconds.
