(b) The open-loop transfer function (OLTF) of a unity feedback servomechanism system is given by: G(s)H(s) = K(s + 10) $3 where K is the open-loop gain. ) investigate the condition(s) for the stability of the OLTF using the contour mapping technique and the Nyquist stability criterion. [7 marks] (i) sketch the Nyquist diagram of the system in the GH(W)-plane and investigate the system's behaviour for varying Kvalues. [6 marks) (i) using the results from Part (ii) show that the system is stable for K > 5.F. Validate your answer using the Routh-Hurwitz stability criterion. [4 marks] (iv) determine the gain margin and phase margin when K = 7.A. Comment on the relationship between the phase margin and the transient response of the servomechanism control system. [Take wge = 12.0B rad/s]. [6 marks)
