异步电动机具有非线性、强耦合、多变量的性质，要获得良好的调速性能，必须从其动态模型出发，分析异步电动机的转矩和磁链控制规律，研究高性能异步电动机的调速方案。矢量控制就是基于动态模型的高性能的交流电动机调速系统的控制方案之一。所谓矢量控制，就是通过矢量变换和按转子磁链定向，得到等效直流电动机模型，在按转子磁链定向坐标系中，用直流电动机的方法控制电磁转矩与磁链,然后将转子磁链定向坐标系中的控制量经变换得到三相坐标系的对应量，以实施控制。-Asynchronous motor with nonlin

针对永磁同步电机的传统直接转矩控制中的磁链和转矩脉动大的缺点,提出了十二扇区细分的磁链闭环控制方法和相应的电压开表。分析了电压矢量对电磁转矩和定子磁链的作用,得到有限的扇区和电压矢量会造成转矩和磁链脉动大。理论和实验对比分析了六扇区划分和十二扇区划分的控制性能。实验结果表明十二扇区划分的PMSM直接转矩控制方法,既保证了DTC的快速性,又很好地降低了转矩与磁链脉动。
