Use MATLAB to simulate the output response of the closed-loop system subject to a unit step input. Explain the effect of adding an additional pole to the transfer function on

the response of the system. Include all the MATLAB codes and any figure in your answers. Now, let us change the transfer function G(s) to G(s) = s+5 /s (s+3) i.e. an additional zero (s = -5) is added to the transfer function. Answer the following questions:
