| 摘 要： | 通过对零电压矢量的分析，明确了零电压矢量在永磁同步电机控制过程中的作用，在对无零电压矢量和有零电压矢量的控制方式行比较的同时，提出了添加零矢量的双滞环方法，并介绍了控制系统中各个环节的MATLAB/Sinmlink建模方法，试验结果表明，双滞环零矢量控制系统转速，转矩响应性能都要优于传统有零矢量直接转矩控制系统。

| Abstract: | The theory of direct torque control (DTC) with zero voltage vectors applied in permanent magnet synchronous motor (PMSM) is proposed in this paper. The function of zero voltage vectors is proposed in the control method. The comparison between DTC with zero vectors applied and DTC without ones is analyzed. A control scheme using zero voltage vectors with double hysteresis loops is put forward for DTC of PMSM. The model of DTC of PMSM based on MATLAB/Simulink is introduced. Simulation results indicate that the DTC with double hysteresis loops method is superior to the traditional controller in speed and torque response. |
