| 摘 要： | 介绍了一种恒定开关频率的永磁同步电机直接转矩控制方法,通过定子磁链及幅值给定、定子电流来计算在恒定开关周期内加在电机定子绕组上的电压,采用空间电压矢量调制方法使逆变器的开关器件处于恒定的工作频率.开关频率越高,其控制性能越好.仿真结果验证了方法是有效的.

| Abstract: | A new method of the direct torque control(DTC) of permanent magnet synchronous motor with constant switching frequency is presented in this paper.Based on stator flux and magnitude given,and the stator current,the stator voltage needed in the switching period is calculated.And then the space voltage vector pulse width modulation method is adopted to keep the switching frequency constant.The higher the switching frequency is,the better the performance is.The simulation result illustrates the effectiveness of the proposed method. |
