A process is described by the transfer function

Find the range of controller settings that yield stable closed-loop systems for:
(a) A proportional-only controller.
(b) A proportional-integral controller (Ï„_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?
