CP4.10 Consider the closed-loop system as depicted in Figure CP4.10. The controller gain K can be modified to meet the design specifications.
a) Determine the closed-loop transfer function Ts = Ys/Rs.
b) Plot the response of the closed-loop system for K = 5, 10, and 50.
c) When the controller gain is K = 10, determine the steady-state value of v(t) when the disturbance is a unit step, i.e., when Ts = 1/s and Rs = 0.
