摘要： Smith预估控制是解决时滞系统控制的有效方法，但其对系统模型参数的精确要求限制了其应用。而模糊控制本质上属于PD控制，无法消除系统的稳态误差。文中设计了一种自校正模糊Smith 控制器，结合模糊控制、Smith预估器及自校正控制的优点，既保持了模糊控制鲁棒性较强的特点，又消除了系统的稳态误差，且改善了系统的动态性能。仿真结果表明了自校正模糊控制器的有效性和优越性。
关键词: 模糊控制, Smith预估器, 自校正控制
Abstract: 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 adaptiveFuzzy-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 adaptiveFuzzy-Smith controller.
Key words: fuzzy control, Smith predictive controller, adaptive controll
