i. i. Given the unity feedback system of Figure 2.2 with: a. Plot the Bode diagram of G(s) using asymptotes. b. Find the gain and phase margins. 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. Imaginary Axis 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. 1 2 0.8 28 D.2 G(s) = D 10(s + 1) s(s+3)(s²+s+30) -02 -0.8 T Nyquist Diagram -0.3 -0.6 -04 0.20 02 04 0.5 RealAxis Figure 4.1 9
