| 摘 要： | 设计了模糊控制调节电压矢量占空比的永磁同步电机直接转矩控制系统，采用开关表选择电压矢量，采用模糊控制器调节电压矢量的占空比。仿真结果表明模糊控制调节电压矢量占空比的永磁同步电机直接转矩控制系统运行良好，可以实现永磁同步电机驱动系统的四象限运行。与直接转矩控制和传统模糊直接转矩控制相比，模糊控制调节电压矢量占空比的直接转矩控制策略可有效减小磁链和转矩脉动，降低电流谐波含量，但增大了平均开关频率。

| Abstract: | Permanent magnet synchronous motor (PMSM) direct torque control (DTC) system based on fuzzy control to adjust the duty ratio of voltage vector is proposed in this paper. The applying voltage vector is determined by conventional DTC switching table. The duty ratio of applying voltage vector is adjusted by fuzzy controller. Simulation results show the proposed fuzzy control system can work properly. Compared with switching table and fuzzy direct torque control, the proposed strategy can decrease stator flux and torque ripple, total harmonic distortion (THD) of stator current, but it increases average switching frequency. |
