英文摘要：

The paper applies sliding mode control theory about switched systems with actuator saturation into the study of the controller system of turntable.Based on the theory about switched systems with actuator saturation,the paper not only designs sliding mode function of switched system with actuator saturation using the method of system dimension reduction in order to guarantee the asymptotically stability on sliding mode and the good quality of the application of sliding mode,but also designs sliding mode controller on switched systems to make controlled systems satisfy given conditions after the adaptive law acts on actuation item.Finally,the method is applied to the designing of turntable servo＇ control systems,and the simulation results show the good dynamic performance and robustness of the method.
