A unity feedback system has the loop transfer function

(a) Determine the phase margin of the system when K = 0.16. (b) Use the phase margin to estimate £ and predict the overshoot, (c) Calculate the actual response for this second-order system, and compare the result with the part (b) estimate.

L(s) = Gc(s)G(s) = s(s + 0.2)
