| 摘 要： | 首先将内埋式永磁电机的数学模型转化为一种表贴式永磁电机模型的等效形式，在此基础上提出了一种静止和低速时的位置观测器。此方法采用高频的旋转矢量电压注入到电机的定子绕组中，通过对高频电流建立模型参考自适应的模型进行位置跟踪，从而取代通过电流滤波方法跟踪位置，该方法可以有效的区分正D轴和负D轴的位置。最后建立了此算法的仿真模型，仿真结果验证了方法的有效性。

| Abstract: | The model of the interior permanent magnet synchronous machine(IPMSM) is transformed to a new structure,which can be equivalent as a surface permanent magnet synchronous machine(SPMSM).Based on the new model,novel methods for position estimation during standstill and low speed are presented for IPMSM drives.Carrier-signal-injection is used,persistent,rotating vector,carrier frequency image tracking techniques to reliably identify and track the orientation of the d and q axes even when the rotor is at stands... |
