| 摘 要： | 直接转矩控制(DTC)对于异步电机而言，它能产生快速及好的鲁棒性响应。介绍了一种新的对于无速度感应电动机基于空间矢量(SVM)模型的直接转矩和磁链控制，它能降低稳态时力矩、磁链和速度的波动，在全速度范围无速度传感应用中将产生更好的稳态性能的同时保留DTC的暂态优点。仿真结果显示，该方法有着比传统的DTC更好的性能。

| Abstract: | Direct torque control (DTC) is known to produce quick and robust response in ac drives.This paper introduces a new direct torque and flux control based on space-vector modulation (DTC-SVM) for induction motor sensorless drives.It is able to reduce the torque ,current,and speed pulsation during steady state.It is concluded by simulation results that the proposed control produce better results for steady-state operation than the classical DTC for a wide speed range,and the DTC transient merits are preserved. |
