DISCRETE COMPENSATION OF SAMPLED-DATA AND CONTINUOUS CONTROL SYSTEMS

摘要

This paper presents a method of compensation, to be applied to con¬tinuous as well as to sampled-data systems, which reduces to zero any over¬shoot or error after a prescribed finite time. This prescribed response is applicable to step or ramp inputs and could be extended to acceleration or higher order inputs. It is shown that this response can be accomplished using the modified z-transform which yields the systems response for all instants of time.
