摘要 基于异步电机在两相坐标系里的状态方程,通过检测电机的定子电压、电流和转速信号,而不需要转子磁链信号,利用最小二乘法递推算法对电机参数进行了辨识,由于不需要转子磁链,这样通过观测得到的磁链就不会影响辨识的准确性,消除了参数计算和磁链观测之间的耦合,仿真结果和实验验证了辨识的准确性。 A parameter identification of IM drive is introduced. The method just uses the stator currents, stator voltages, and velocity, makes real time identification of induction motor parameters based on the Least Square algorithm, and does not use the rotor flux signal, avoiding the coupling between the rotor observation and the parameter identification. The performance of the proposed scheme is verified through simulation and experiment.
