        摘 要:針對無軸承電機在高速傳動領域使用中存在的問題,提出來一種基于空間電壓矢量調制的直接轉矩控制方法。建立了無軸承異步電機的數學模型,構建了以懸浮繞組模塊、旋轉繞組模塊和氣隙磁場計算模塊為主要構成的系統框圖。仿真結果表明,通過使用SVM-DTC 的控制方法,無軸承異步電機能夠具有較好的動靜態性能,但是不可避免地產生了速度的超調及轉矩和磁鏈的波動。

        Abstract: Aiming at the use of bearingless motor in the high speed transmission field, this paper proposed a kind of direct torque control method (DTC) based on space voltage vector modulation (space voltage vector modulation). The mathematical model of bearingless induction motor was established. The system block diagram included the suspension winding module, the rotating winding module and the air gap magnetic field calculation module. The simulation results show that the bearingless induction motor is in possession of better static and dynamic performance, unavoidable overshoot of velocity and fluctuation of torque and flux linkage.
        Key words: bearingless induction motor; space voltage vector modulation-direct torque control; MATLAB
