Abstract
To solve the problem of inductance parameter change caused by core saturation and cross-coupling effect of synchronous reluc-tance motor,the traditional sensorless control method based on sliding mode observer is difficult to achieve high performance control with fixed inductance parameter,an adaptive sensorless control strategy based on super-twisting sliding mode observer is proposed,and the stability con-ditions of the proposed control scheme are given.Static motor flux saturation data is obtained through finite element simulation,which can be used to fit the proposed motor flux saturation model.Then,the obtained saturation model is applyed to the observer to solve the problem of in-ductance parameter changes.Finally,the effectiveness and excellent control performance of the proposed sensorless control method are veri-fied by simulation.关键词
