Question
(b) A system has the closed-loop transfer function s(s + 1) G(s) = (s +3)(s² – 4s + 13) Sketch the Pole-Zero plot for this system. Comment on the stability and response characteristics of the system. A PD controller with proportional gain K, and derivative gain Ka is in series with a plant with the transfer function (c) 4 G(s) = s+0.5 and employs a unity negative feedback loop. Find suitable values for K, and Ka so that the closed-loop system has a time constant t = 4 see, and the closed- loop response to a step input is 0.98. Find the range of K, for which the closed-loop system shown in Figure Qld is stable. (d) R(s) C(s) s+8 (s+1)(s + 5) Figure Qld
