摘要

永磁同步电机在弱磁工况下动态性能不佳。分析了传统磁链弱化策略的不足，在传统磁链弱化策略的基础上增加了补偿器。利用q轴基准电流与实际电流的差来设计补偿器。采用该方法，可以同时实现反卷动控制和弱磁控制。仿真和实验结果验证了该消通量策略的有效性。

An improved flux-weakening strategy for field-oriented-controlled PMSM drives

The permanent magnet synchronous machine (PMSM) dynamic performance is not good in the flux-weakening operation region. The drawbacks of the conventional flux-weakening strategy were analyzed, and a compensator was added to the conventional flux-weakening strategy. The compensator is designed by using the difference of the q-axis current reference and the real current. With this method, the anti-windup control and flux-weakening control can be achieved simultaneously. The simulation and experimental results are used to demonstrate the effectiveness of the proposed flux-weakening strategy.
