E9.12 A unity feedback system with the loop transfer function

Ge(s)G(s) = K s(1718)(1 + T28)' where = 0.01 and T2 = 0.3 s. (a) Select a gain T1 K so that the steady-state error for a ramp input is 20% of the magnitude of the ramp function A, where r(t) = A(t), t0. (b) Obtain the Bode plot of loop transfer function, and determine the phase and gain margins. (c) Determine the bandwidth wg, the reso- nant peak Mp, and the resonant frequency w, of the closed-loop system.
