摘要
为了探究永磁电机弱磁控制原理,提升弱磁控制性能,对永磁电机的3种控制策略进行了对比分析,着重分析了高速弱磁区控制方法和性能,并进行了仿真和试验研究。研究结果表明,基于空间电压矢量调制的直接转矩控制技术在高速弱磁区控制性能最优,是未来工程应用研究的主要方向。
In order to explore the flux weakening control principle of PMSM and enhance its performance,three control technologies were compared and analyzed,emphasis on high-speed flux weakening control method and performance,as well as the simulation and experimental study was carried out.The results showed that：direct torque control technology based on the space voltage vector modulation had excellent performance in the flux weakening area,which would be the main direction of future application.
