Adaptive-Fuzzy-Smith Controller Design of a Class of Systems with Time Delay

Smith predictive controller is an effective method to control the time delay systems,however,the drawback of high rigourness of Smith controller limits its application.Fuzzy-Smith control belongs to PD control and can't avoid the steady-state error.An adaptive-Fuzzy-Smith controller is designed,combining the advantages of fuzzy control,Smith predictive control and adaptive control,it keeps the good robustness of fuzzy control and improves the dynamic performance of the system.The simulation results show the effectiveness and superiority of the adaptive-Fuzzy-Smith controller.
