Consider a plant with transfer function as 1 G(s) s3 + s2 +3s +1 Its closed loop transfer function with P-Controller C(s) = Kp is C(s)G(s) s3 + s2 + 3s +1+ Kp GCL(s) 1+ C(s)G(s) a) Show the graph with step response of Gca with Kp= 1 b) Show the graph with step response of Gu with Kp=5 c) In your own words explain the difference produced by different value of Kp.
