1. Design a PI controller to drive the step response error to zero for the unity feedback system shown in Figure P9.1, where $G(s)=\frac{K}{(s+1)(s+3)(s+10)}$ The system operates with a damping ratio of 0.5 . Compare the specifications of the uncompensated and compensated systems. [Section: 9.2] PIUUKE PYy. I
