摘要：

针对永磁同步电动机脉振高频注入法估计直轴正方向判定存在180°电角度误差的问题,提出一种基于脉振高频注入的电机估计直轴正方向判定与补偿方法。在初次得出直轴位置估计的基础上,考虑4个导致位置估计失败的转子初始位置角,通过改变它的初始位置估计给定,维持系统正常运行。利用不同磁极下(N极和S极)去磁和增磁效应导致的定子直轴等效电路时间常数不同的特点,判定实际直轴正方向,对初始位置估计角进行有效电角度补偿。实验结果验证了该估计直轴正方向判定方法的有效性。

Abstract:

Since estimated direct axis positive direction of permanent magnet synchronous motor based on fluctuating high frequency injection method exists 180° electric angle error, a method to determine the positive direction and compensate based on fluctuating high frequency injection was proposed. On the basis of getting the first estimated position, four initial position angles that cause the position estimate to fail were considered, and the initial position estimate given were changed to maintain the system to run normally. The equivalent circuit time constant of the stator direct axis were different with demagnetization and magnetization effects of different magnetic poles (N and S poles), then the positive direction of actual direct axis was determined, and the effective electrical angle compensation was made for the initial position estimation. Experimental results verified the validity of the proposed method to determine the positive direction of estimated direct axis.

Key words: permanent magnet synchronous motor, fluctuating high frequency injection, positive direction of estimated direct axis, position compensation
