摘　　要：感应电动机矢量控制系统中,转子电阻的变化严重影响着系统的运行性能。对转子电阻的变化进行实时检测和辨识是提高系统性能的重要保证。针对感应电动机的矢量控制系统,基于无功功率模型,采用模糊控制以及模型参考自适应理论,提出了一种电机转子电阻的模糊自适应辨识新方法。该方法采用模糊控制技术对自适应机构的参数进行调整,设计了自适应律。系统仿真结果证明了该方法在转子电阻辨识中的有效性。The variation of rotor resistance in induction motor affects the performance of the vector control system greatly. To detect and identify the changes of rotor resistance online was an important guarantee to improve the system performances. A novel fuzzy adaptive rotor resistance identification method was proposed. In this method, based on instantaneous reactive power model, the MRAS was combined with the fuzzy logic theory ; a fuzzy controller was designed to adjust the parameters of the adaptive mechanism of MRAS. The simulation results showed the effectiveness of this method when being used in the vector control system of induction motor.
