Question

A system with unity feedback is shown in figure (2), where G(s)= 8/{s(s+3)}. Calculate the percentage of overshoot, settling time (2% criterion),rise time and the steady state value of the

response of the output of the closed-loop system when the input is a unit-step input. Also, use MATLAB to simulate the output response and validate your calculations. Include all the MATLAB codes in your answers.
