Determine:
Q: a) The values of K and k of the closed-loop system shown in Fig so that the maximum overshoot in unit-step response is 25% and peak time is 2 sec., assume that J=1 kg-m^2 . Consider a unity-feedback control system with the closed loop transfer function.
b) Whether system is stable or not.
c) The steady state error for unit step input if system is stable.
