| 摘 要： | 从理论上分析了传统直接转矩控制方案中电压矢量对转矩脉动的影响,针对这一导致电机低速时脉动过大的原因.介绍了基于离散空间矢量调制的直接转矩控制方法.该方法通过将控制周期分为多个时间段.分别细化输出不同电压矢量以达到控制效果优化.并给出了相应的开关表.使用FPGA芯片来实现该方案,实验表明该直接转矩控制方案取得了较好的控制效果.

| Abstract: | Motor under control of traditional DTC vibrates seriously when the motor's speed is slow.This paper gives the reason of that and introduces the control system based on DSVM-DTC(Discreted space vector modulation-Direct torque control) which divides the control period into several sections and in each section different voltage vector is selected instead of unchangeable voltage vector selected in entire control period,the corresponding switch table is figured out.It is carried out by the FPGA design at last.Th... |
