10 3 dB 3 dB 6 dB po dB 0 -6 dB -7 12 dB -20 dB Gain (dB] -40 dB -60 dB -270 -180 -146 -90 0 Phase (deg] Consider a Nichols plot of some proper system P(s). The gain crossing frequency is Wg = 1 [rad/s) and the phase crossing frequency is W p. The system is controlled in standard closed-loop with unity feedback. For C(s)=1 what is the steady state error @ ss of the closed-loop system for step reference signal r = 1(t)? Answer: For C(s)=1. what is the maximal gain of the closed-loop complementary sensitivity function frequency response|T (W) Answer: Design a controller of the form C(s)=k Clead(s)Clag(s) such that the crossover frequency is Wc=Wo=3.5 [rad/s) and P.M.=45 What is k?
