A process is described by the transfer function G(s)=1/{(5s+1)(s+1)} Find the range of controller settings that yield stable closed-loop systems for:(a)A proportional-only controller.(b)A proportional-integral controller (?I=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.
