摘要:
 感应电机转子时间常数受温度、磁饱和等因素的影响,导致矢量控制系统中转子磁场定向出现偏差,进而使感应电机的输出转矩发生振荡。为此提出了一种基于磁链优化模型的感应电机转子时间常数在线辨识方法,以定子电流和定子磁链的点乘作为设定物理量来构造一个模型参考自适应系统,并对未考虑直流偏量影响的定子磁链观测器进行改进。最后,在Matlab平台对该方法进行仿真研究,结果证明了该方法的有效性。
Abstract:
 The rotor time constant of induction motor is affected by temperature, magnetic saturation and other factors, which leads to the deviation of rotor field orientation in vector control system, and then the output torque of induction motor oscillates. In this paper, an online identification method of induction motor rotor time constant based on flux optimization model is proposed. A model reference adaptive system is constructed by dot product of stator current and stator flux as the set physical quantity, and the stator flux observer without considering the influence of DC bias is improved. Finally, the method is simulated on MATLAB platform, and the results show that the method is effective.
