(b) The open-loop transfer function (OLTF) of a unity feedback servomechanism system is given by: K(s + 102 G(s)H(s) 53 where K is the open-loop gain. (1) investigate the condition(s) for the stability of the OLTF using the contour mapping technique and the Nyquist stability criterion. [7 marks] (ii) sketch the Nyquist diagram of the system in the GH(W)-plane and investigate the system's behaviour for varying K values. [6 marks]
