Each item below describes key characteristics of a particular system (that is, a plant transfer function) For each system, describe the effect of proportional control on the stability of the closed-loop system. Specifically, 1) what can you say for small gains, and 2) what for large gains? (E.g., stable, unstable, inconclusive.) Provide a short explanation of your answers, with sketches as necessary. (a) (b) Right-half plane pole. (Other poles, zeros unknown.) Four poles, one zero. (c) Right-half plane zero. (Other poles, zeros unknown.) (d) Relative degree one, some unstable poles, all zeros in left-half-plane.
