| 摘 要： | 针对异步电动机直接转矩控制(DTC)系统存在转矩和磁链脉动等缺点,提出一种基于离散空间矢量调制(DSVM)的DTC系统。根据转矩、磁链误差和速度的不同,在高低速应用不同的开关表,达到改善异步电动机运行性能的目的。仿真结果表明,利用该方法可明显改善异步电动机的电磁转矩脉动。

| Abstract: | A discrete space vector modulation(DSVM) method was developed to solve the problems of direct torque control(DTC) for induction motors related to flux ripple and torque ripple. Based on the different speed, torque and flux errors, the different switching tables of inverter were applied to improve drive performance of induction motors. The simulation results testified that torque and flux ripples were small with a DSVM. |
