摘　　要：针对永磁同步电动机在传统直接转矩控制中存在较大转矩脉动的缺点,提出一种基于模糊控制的永磁同步电机直接转矩控制方法.该方法运用模糊控制器代替传统的滞环控制器,实现转矩和磁链的低脉动效果,并通过Matlab/Simulink中FIS工具箱对基于模糊控制的PMSM直接转矩控制系统进行建模仿真.结果表明,基于模糊控制策略的直接转矩控制性能远优于传统直接转矩控制.According to the disadvantage of big torque ripple in conventional direct torque control of permanent magnetic syn- chronous motor （PMSM）, a PMSM direct torque control （DTC） method based on fuzzy control was proposed. The conv- entional hysteresis controller was replaced by fuzzy controller, which has low torque and small flux ripples. Fuzzy direct torque control system was simulated based on Matlab/Simulink FIS toolbox. Results show that the performance of fuzzy direct torque control is more superior to that of the conventional direct torque control.
