【摘要】 根据离散滑模控制理论和专家、模糊控制理论，针对矢量控制的交流伺服系统，设计了一种离散专家－模糊滑模控制器，即在离散滑模控制器后加一个积分环节再与专家模糊控制器相结合，有效地削弱了单纯滑模变结构控制系统的“抖振”．可见，由该离散专家模糊滑模控制器构成的交流伺服系统，具有良好的快速性和抗负载扰动、参数摄动的鲁棒性．更多还原

【Abstract】 This paper designs a discrete expert-fuzzy sliding mode controller by discrete sliding mode control theory and exper-fuzzy control theory for a vector control AC servo system. The method of link inserting an integral loop behind a discrete sliding mode controller with a expert-fuzzy controller. It effectively decreases the chattering of only using a sliding mode variable structure control system. Result shows that AC position servo systom of a discrete exped-fuzzy sliding mode control has good fastness and robustness of the disturbance of load and parameters.更多还原
