Consider a plant with transfer function as G(s) = s+2 Its closed loop transfer function with P-Controller with KP 3 is C, (s) = Kp = 3 GCL1(s) =5 While its closed loop transfer function with P-Controller and PI controller is given by 3s+1 C2(s) = Kp + = 3+- GC12(s) %3D %3D %3D s2+5s+1 a) Show the graph with step response of GcLI b) Show the graph with step response of GcL2 c) In your own words explain the difference produced by using P controller in GcL1 and the combination of P and PI controller in GcL2.
