摘　　要：研究一个将模糊逻辑控制与滑模控制相结合的控制策略。通过模糊控制策略获得一个等效控制器,在模糊逻辑控制规则中,使用边界层(滑模)方法设计了一个对相应的参数在线自适应调整算法,避免系统的抖动问题,并获得了准确的轨迹跟踪。仿真研究表明,设计的自适应模糊滑模控制器,在存在未知扰动的情况下表现良好。An adaptive fuzzy sliding mode control scheme for traveling-wave ultrasonic motor was proposed,it combined a fuzzy logic with the sliding mode control.An equivalent controller was obtained by the fuzzy control strategy.In the sliding mode rule,an online adaptive parameters adjustment algorithm was designed by using the boundary layer method.The controller could avoid the jitter of the system and obtain accurate trajectory tracking.Simulation results have shown that the presented adaptive of fuzzy sliding mode controller performs well in the presence of unknown disturbances.
