摘　　要：文章将模糊逻辑控制和滑模变结构控制两者有机结合 ,为矢量控制交流伺服系统提出并设计一种新型位置控制器。它由一维模糊控制器和一维模糊逻辑推理机构两部分组成 ,模糊控制规则由滑动模态到达条件得到。该控制器具备模糊控制与滑模控制两者的优点 ,同时较好地解决了滑动模态的抖动。仿真结果表明In this paper, based on fuzzy logic control and sli d ing mode control theory, a novel position controller is proposed for vector cont rolled AC servo drive. The controller is composed of one-dimensional fuzzy cont roller and one-dimensional fuzzy reasoning mechanism. The fuzzy logic control r ules are derived from the sliding mode reaching condition. The controller owns the merits of the two control methods and avoids respective drawbacks. Simulati on results show that it can obviously improve the controlled system performance.
