(a) A control system is modelled by the transfer function G(s) = s +5 (i) Find its analytical expressions of both magnitude frequency response and phase frequency response. (ii) Let G2 (s) = Ks where K is a positive gain. Using the results obtained in (i), determine the analytical expressions of both the magnitude and phase frequency responses of G; (3)G2(s). Then, briefly discuss how the value of K affects the magnitude and phase frequency responses of G (s)G2(3), respectively. [8 marks]
