Question: 11. Consider a feedback system in which a phase-lead compensator 500 G(s)= (s+1)(s+5)(s+10) The feedback system is a negative unity feedback control system shown in

11. Consider a feedback system in which a phase-lead compensator

500 G(s)= (s+1)(s+5)(s+10) The feedback system is a negative unity feedback control

500 G(s)= (s+1)(s+5)(s+10) The feedback system is a negative unity feedback control system shown in Figure 10.38. Compute the gain and phase margin. a. G.M. dB, P.M. = 60 b. G.M. = 20.5 dB, P.M. = 47.8 c. G.M. = 8.6 dB, P.M. = 33.7 d. Closed-loop system is unstable.
