摘　　要：永磁同步电动机采用id=0矢量控制方法,实现了电流的静态解耦,但动态耦合关系依然存在,这造成了动态过程中电流分量互相影响,尤其在高加减速过渡过程中动态耦合影响更为显著,使电动机的动态性能变差。归纳总结了3种基于矢量控制的电压解耦策略,理论分析其各自控制原理和特点,并对每种解耦方法进行仿真对比研究,最后通过仿真实验验证了理论分析的结果。The method id=0 is one of vector control′s methods of PMSM.The method makes current decouple in a static state,but dynamic coupling between d-q current still exist,which causes d-q current effect on each other in dynamic process and also causes a bad dynamic performance of PMSM.The problem of dynamic coupling has particularly outstanding when PMSM highly accelerates/decelerates.Three voltage decoupling methods was summarized which based on vector control,by means of theoretical analysis and simulation studying,contrasts the performance of different voltage decoupling methods,in the end,simulation results confirm the theoretical analysis.
