永磁同步电机直接转矩控制中引入SVPWM技术后,磁链和转矩脉动明显减小,且速度响应明显加快。这是由于传统的DTC系统釆用滞环控制器,每个周期选择一个幵关电压矢量,不能完全补偿转矩和磁链的误差 而后者采用PI控制器和SVPWM调制,可选择多个基本电压矢量来合成任意的电压矢量,能够更好的补偿误差。仿真结果说明,基于SVPWM的DTC系统在磁链幅值响应以及转矩响应上的改善效果很明显。-the impact of space voltage vector of the stator flux and t

传统的PMSM DTC系统因为把磁链的空间均匀的分成了六个部分,并且使用了滞环控制器来控制磁链和转矩,所以不可避免的存在着较大的转矩脉动和磁链脉动等问题。在磁链处在扇区分界处时,它的增量明显不对称,所以在PMSM DTC系统设计时很有必要降低磁链在边界处的不对称性,从而达到减小转矩脉动的目的。本章在分析PMSM DTC系统存在的转矩和磁链脉动问题的基础上,深入研究了一种新型的控制方法,就是把磁链的扇区进行细分,仿真结果表明,在采用扇区细分控制策略以后,PMSM DTC能够获得良好的动态性能,转
