交流感应电机参数辨识方法的综述

The Overview of AC induction motor parameter identification methods

在矢量控制和直接转矩控制系统,电机参数准确性决定了系统控制性能。本文介绍了当前交流感应电机参数辨识的方法,例如有限元分析、递推最小二乘法、扩展卡尔曼滤波、模型参考自适应、人工神经网络和遗传算法等。最后介绍了参数离线辨识和在线辨识的作用。

In the vector control and direct torque control,the motor parameter determine the accuracy of the performance of the system.The article describes the current AC induction motor parameter identification methods, such as finite element analysis, recursive least squares method, extended Kalman filtering, model reference adaptive, artificial neural networks and genetic algorithms.Finally, it describes the ruction of off-line idetificatio and on-line idetification.
