摘要
本文介绍了一种新的对于无速度传感器感应电动机基于空间矢量(SVM)模型的直接力矩和磁链控制。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在产生更好的稳态性能的同时保留了 DTC 的暂态优点。仿真结果显示本方法有比传统的 DTC 更好的性能。
This paper introduces a new direct torque and flux control based on space-vector modulation(DTC-SVM)for a speed sensor-less induction motor.It is able to reduce the torque,current,and speed pulsing during steady state.It is concluded by simulation results that in the proposed control produce results for steady-state operation is better than the classical DTC for a wide speed range,and the DTC transient merits are preserved.
