Q3. (a) An automobile speed control system will be necessary for passenger cars travelling on the automatic highways of the future. As a design engineer, suggest a control system model for a standard automobile and concisely discuss the possible analysis and design procedure that you would recommend in order to achieve an effective speed control system. [7 marks] (b) The open-loop transfer function (OLTF) of a unity feedback servomechanism system is given by: K(s + 10)2 G(s)H(s) = 53 where K is the open-loop gain. (i) investigate the condition(s) for the stability of the OLTE 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]
