The transfer functions of the control system shown in Figure Q1a are as follows: K (s + 5) Gc(s) = (s + 3)2 Gp(s) = and H(s) = 1. (s + 1)(8 + 4) R(s) r(t) + E(S) e(t) Gc(s) Ge(s) C(s) c(t) H(S) Figure Q1a (8 marks) (c) Derive an expression for the open-loop frequency response of the system with respect to K for w0 and 0 - and hence, show a simple Nyquist sketch of the open-loop response of the system.
