Abstract

This paper proposes a new design method for a sampled-data multirate control system, in which the sampling interval of the plant output is an integer multiple of the hold interval of the control input. An existing control law which stabilizes a closed-loop system is extended such that the sample response is maintained and integral compensation is revealed only when there is a modeling error or a disturbance. The transient response is not deteriorated by the integral compensation when neither a modeling error nor a disturbance exists because the proposed method is designed as a two-degree-of-freedom system.
