Given the unity feedback system of Figure 2.2 with: 10(s + 1) G(s) = s(s+ 3) (s² + s + 30) a. Plot the Bode diagram of G(s) using asymptotes. b. Find the gain and phase margins. i. The Nyquist diagram of the forward-path transfer function G(s)/K of a unity feedback control system is shown in Figure 4.1. Find the following performance characteristics of the system: a. Gain margin (dB) when K=1. b. Phase margin when K=1. c. The value of K so that the gain margin is 20dB. d. The value of K so that the system is marginally stable. e. Steady state error when the reference input is a unit-step function. Nyquist Diagram 1 0.8. 0.6 i.
