| Abstract |
This paper presents high performance control techniques of permanent magnet synchronous motor byusing a real-time simulator with a finite element analysis based motor model. These techniques enableto consider nonlinear characteristics of PMSM in motor drives because FEA based motor model cantakes into account of spatial harmonics and magnetic saturation. Therefore, these techniques take someadvantages for development control method and drive system. In this paper, high performance torquecontrols for PMSM are proposed as one of the advanced control techniques given by the real timesimulating with the FEA motor model. The proposed torque controls are developed based on directtorque control (DTC) of PMSM and output torque and stator linkage flux estimator using FEA basedmotor model. The proposed method can achieve both fast torque reference and smooth torque withreducing pulsation torque which is generated spatial harmonics neglected in the conventional DTCmethod. The effectiveness of proposed method is verified by performing some simulations andexperiments |
