Determine the proportioanl gain constant Kp and T such that the bandwidth of the closed-loop system is around 0.55 rad/sec and an overshoot of around 9%. Note that the closed-loop bandwidth is close to the gain crossover (cut-off) frequency. Check your design in both frequency and time domain and comment. Determine the maximum overshoot and settling time. Determine as well, using a Bode diagram, the expression of the stead state closed loop output for a sinusodial input with 0 deg...
