0.6- 0.4 -0.2- -06 -0.8 Nyquist Diagram -0.5 D 0.5 Real Axis Figure 2: Nyquist plot for Question 6. (a) Is the closed loop system stable for K 1? Explain your answer. (b) (c) What is the definition of gain margin? Particularly, what is the gain margin of the system with K = 1? Explain your answer. The Nyquist plot goes through the point (-0.5,0). Find the value of s in G(s) that corresponds to that point. 6. Frequency-Domain Control Design Consider the unity feedback system shown in Figure 1. The Nyquist diagram for the plant G(s) s258-4 2(s² +58 +6) (with gain K = 1) is given in Figure 2. R(s) Y(s) K G(s) + Figure 1: Unity feedback system for Question 6.
