A unity feedback system with the forward transfer function G(s)=K/(s+1)(s+3)(s+6) is operating with a closed-loop step response that has 15% overshoot. Do the following:

a) Evaluate the steady-state error for a unit step input

b) Design a PI control to reduce the steady-state error to zero without affecting its transient response

c) Evaluate the steady-state error and overshoot for a unit step input to your compensated system
