摘　　要：针对鼠笼异步电动机间接磁场定向控制系统，提出一种ＰＩ调节器和模型跟踪调节相结合的鲁棒控制方案，用以提高交流电机的驱动性能，抑制参数变化和负载扰动对系统性能的影响．将解耦的感应电机的简化模型作为理想模型，补偿环节的调节使得实际对象动态特性趋近于理想模型的动态特性．理论分析。This paper presents a robust control scheme for a squirrel cage induction motor with an indirect field oriented control system. It is used to improve the performance of an AC drive and to lower its sensitivity to parameter variation and load disturbance. A simplified model for the current decoupled induction motor has been used as an ideal model. The theoretical analysis, the simulation and experimental results show that the PI controller proposed and the model reference complementary algorithm can effectively improve the transient behavior of the system.
