For the unity feedback system given in Figure P9.1 with

do the following:

a. Find the gain, K, for the uncompensated system to operate with 30% overshoot.

b. Find the peak time and K_v for the uncompensated system.

c. Design a lag-lead compensator to decrease the peak time by a factor of 2, decrease the percent overshoot by a factor of 2, and improve the steady-state error by a factor of 30. Specify all poles, zeros, and gains.
