Abstract :
In this paper, a simple yet effective modified Smith predictor control scheme is proposed for periodic disturbance rejection. With sound set point response, the closed-loop regulation performance is enhanced significantly with respect to periodic disturbances, provided that the period of the disturbance and the system time delay can be detected. Internal stability is analyzed explicitly. The effectiveness is demonstrated by simulations.
