摘要
对于矢量控制的交流伺服系统，根据离散滑模控制理论和模糊控制理论，设计了一种离散模糊滑模控制器，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”。仿真实验结果表明由该离散模糊滑模控制器构成的交流位置伺服系统，具有良好的快速性和抗负载扰动、参数摄动的鲁棒性．
This paper designs a discrete fuzzy sliding mode controller with discrete sliding mode control theory and fuzzy control theory for a vector control AC servo system. The method is inserting an integral loop behind a discrete sliding mode controller combined with a fuzzy controller. It effectively decreases the chattering of control system only using a sliding mode variable structure. Simulation and experimental result shows that AC position servo system of a discrete fuzzy sliding mode control has good fastness and robustness of the disturbance of load and parameters.
