Question:

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.

(c) What can you say about the effect of adding the integral mode 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.
