(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(jw)-plane and investigate the system's behaviour for varying K values. [6 marks) (ili) using the results from Part (li) show that the system is stable for K > 5.F. Validate your answer using the Routh-Hurwitz stability criterion. [4 marks)
