E10.11 A unity feedback system has

G(s) = 9 s(s +0.1)(1+0.2s)* A lead network is selected so that Ge(s) = (1 + 0.2998) (1+0.0299s)" Determine the peak magnitude and the bandwidth of the closed-loop frequency response using (a) the Nichols chart, and (b) a plot of the closed-loop fre- quency response.
