表贴式永磁同步电机无传感器控制的在线多参数辨识方法

The performance of the model-based sensorless technique depends on the accuracy of model parameters. Parameter errors between the model and the machine may result in the estimation error of the rotor position, and then degrade sensorless control performance. This article proposes an online multiparameter identification method, which is able to estimate the resistance error, inductance error, perma...
