CP8.5 A block plot of a second-order system is shown in Figure CP8.5. 

(a) Determine the resonant peak Mpω the res

onant frequency ωr, and the bandwidth ωB, of the system from the closed-loop Bode plot. Generate the Bode plot with an m-file for ω = 0.1 to ω = 1,000 rad s using the logspace function.

(b) Estimate the system damping ratio, ζ, and natural frequency ω.

(c) From the closed-loop transfer function, compute the actual ζ and ωn and compare with your results in part (b).
