Quick methods for evaluating closed-loop poles

G. Biernson

Abstract

IT IS GENERALLY necessary to know the closed-loop poles of a feedback control system in order to determine completely its time response. Although the peak overshoot and rise time for a step input can be estimated readily from the closed-loop frequency response of the system, such low-frequency effects as tails in the step response, the settling time of the ramp response, and so on, can be determined best from the values of the closed-loop poles.
