Abstract
Direct torque control technology for permanent magnet synchronous motor (PMSM)based on sliding mode varia-ble structure is provided with merits of simple control structure,fast response speed,strong robustness,and so on,which means a kind of high-powered control method for frequency conversion.Therefore,this paper proposes a kind of PMSM di-rect torque control technology based on fractional order sliding mode variable structure which uses combination reaching law to design the fractional order sliding mode controller,that is to adopt power exponent reaching law in the preliminary of control while variable speed reaching law in the late stage.Simulation result indicates that this control method is able to ef-fectively reduce flux linkage and torque impulse and obviously improve response speed of the system,and has good disturb-ance performance and strong robustness.关键词
