2) a) (5 pts) The magnitude plot of the transfer function K(1 + 0.58)(1+as) G(S) = s(1+ s/8)(1+bs)(1+ s/36) is shown below. Determine K, a and b from this plot and show your steps clearly. Then find the steady state error for a ramp input when G(s) is placed within a unity feedback loop. K b)(15 pts) For the unity feedback system with open loop transfer function G(3) = 6F1js, first plot the general shape of the root locus diagram. Then find the Gain margin using its mathematical 04 - -20 dB/dee +20 dB/ -20 dB/dec O dB/dec 20 logG (6B) 40 dB/doc 24 (rad) definition. Finally, find the closed loop transfer function with K = 1. Draw the approximate magnitude frequency response plot (Bode plot) for this closed loop system. Does this system have a peak resonance Mp ? Why, why not?
