For the unity feedback system of Figure P9.1, with

the damping ratio for the dominant poles is to be 0.4, and the settling time is to be 0.5 second.

a. Find the coordinates of the dominant poles.

b. Find the location of the compensator zero if the compensator pole is at -15.

c. Find the required system gain.

d. Compare the performance of the uncompensated and compensated systems.

e. Use MATLAB or any other computer program to simulate the system to check your design. Redesign if necessary.
