Consider the unity feedback system shown in Figure P9.1 with

K G(s)= %3! (s +3)(s+ 5)(s +7)

a. Design a compensator that will yield K_p = 20 without appreciably changing the dominant pole location that yields a 10% overshoot for the uncompensated system.

b. Use MATLAB or any other computer program to simulate the uncompensated and compensated systems.

c. Use MATLAB or any other computer program to determine how much time it takes the slow response of the lag compensator to bring the output to within 2% of its final compensated value.

K G(s)= %3! (s +3)(s+ 5)(s +7)
