| 摘 要： | 针对永磁同步电机磁链参数易受环境温度、定子电流等参数影响的情况,研究了表贴式永磁同步电机(SPMSM)和采用id=0控制的内置式永磁同步电机(IPMSM)功率、扭矩与磁链的联系,提出了一种基于功率闭环的在线辨识磁链实现精确扭矩控制的策略,并进行了仿真和实验分析. 结果表明,提出的策略能使永磁磁链快速、准确地收敛到磁链真实值,从而提高车用电机驱动系统的动态性能和抗干扰能力.

| Abstract: | The flux linkage of permanent magnet synchronous machines(PMSM) is sensitive to ambient temperature and stator currents. The relationship among power, torque and flux of SPMSM and IPMSM with id=0 control method was studied. A flux estimation strategy based on power closed-loop was proposed. This strategy could lead to a more accurate torque control. The results of simulations and experiments show that the estimated flux linkage in the proposed strategy can follow the real flux-linkage fast and accurately. This strategy shows a good dynamic performance and anti-interference performance in hybrid electric vehicle (HEV) application. |
