交流异步电机状态变量观测及其优化控制

State Variable Observation of Induction Motor and Its Optimal Control

采用维持磁通始终恒定的方法对电机转矩直接控制,可解决交流异步电机控制精度和系统复杂性之间的矛盾,在电机状态变量观测及位置控制中应用了现代控制理论,和传统的矢量控制方法相比,在相同的性能指标下,该系统便于用微机来完成实时控制.

For solving the contradiction between control precision and complexity of system ,the method of keeping the magnetic flux constant is used for direct controlling induction motor . Application of modern control theory in motor state variable observation and place control , comparing with traditional vector control method, in the same function target, contribute to real-time control with microcomputer.
