| 摘 要： | 为解决异步电机控制精度和系统复杂性之间的矛盾，本文采用维持磁通恒定的方法实现对电机转矩的动态控制，并在此基础上实现了位置最优控制。在异步电机磁通的检测中应用了状态观测理论，和传统的矢量控制中的磁通检测方法相比，本磁通观测器具有简单，易实现，且对参数不敏感的特点。

| Abstract: | In order to overcome the contradiction between the complexity and the control precision of a drive system, this Paper realize the torque control of induction motor on the basis of stator flux control. More over, optimal position control of induction motor has been carried out. In the reconstitution of the stator flux, a state observer, not a simple estimator as in the vector control is used, this observer has the advantage of being non sensitive to Parameter variations and easy to realize. |
