为了验证永磁磁阻电机具备宽调速域的优势,同时充分发挥永磁磁阻电机在弱磁运行时的输出转矩,提出了一种基于转矩预测控制的全速域控制方法。采用Ansys设计了一台永磁磁阻电机,并与Simulink联合仿真验证了方法的可行性。验证结果表明:转矩预测控制方法可以使电机在全速域获得良好的动态性能,同时永磁磁阻电机弱磁运行时依然具有优秀的转矩输出能力。

In order to verify the advantages of the PMASynRM with wide speed domain, and give full play to the output torque of the PMASynRM in the field weakening operation, a full speed domain control method based on torque prediction control was proposed. A PMASynRM was designed with Ansys, and cosimulated with Simulink. The results showed that the torque prediction control method could make the motor get good dynamic performance in the full speed area, and the PMASynRM still had excellent torque output capability under field weakening control.
