Q.4 A feedback control system is defined by the transfer function, Y(s) = 22(s + 3) S2 + 8 + 36 R(s) = (a) For a unit step input R(s) = 1/s, determine: the steady state error ess(t) and the steady state output response Yss(t). (10 marks) (b) Determine the poles and zeros of the system and draw them on an s-plane diagram. (6 marks) (c) If a third root was added to give the following transfer function, what the smallest value for a that will allow the complex conguate poles to be dominant? Y(s) R(s) = 22(5 + 3) (s + a)(s2 + 8s +36) (4 marks)
