a.)Determine the values of the
poles and zeros of the closed loop system shown when the controller
gain kc = 0.
answer should be
no zeros
poles at s = 2.0 and -0.5 ± j
b.) Compare these with the open loop poles and zeros.
c.) Now determine the values of the poles and zeros at some very high gain, say kc = 105 .
