摘要
针对永磁同步电动机在运行中电机的电磁参数的改变,通过对永磁同步电动机稳态数学模型的推导,利用递推最小二乘法对电机的电阻、电感进行在线辨识。在Matlab/Simulink中搭建辨识模型进行分析比较,验证该方法可以准确地辨识出电阻、电感的值。递推最小二乘法简单可靠,易于实现,具有一定的实用价值。
For the change of the electromagnetic parameters of the running PMSM, recursive least squares method and the deduction of the steady-state model of PMSM were used to identify the resistance and inductance of the motor online. The accruacy was proved by the comparison and analysis in Matlab/Simulink. It has great practical value because of the reli- ability and easy implement of recursive least squares.
