DYNAMIC BEHAVIOR AND STABILITY OF CLOSED-LOOP PROCESSES Q1. 11.13 A process is described by the transfer function G(s)=(5s+1)(s+1)1 Find the range of controller settings that yield stable closed-loop systems for: (a) A proportional-only controller. (b) A proportional-integral controller (l=0.1,1.0,10.0). (c) What can you say about the effect of adding larger amounts of the integral action on the stability of the controlled system; that is, does it tend to stabilize or destabilize the system relative to proportional-only control? Justify your answer. (K=1,=1)
