Precise torque control and active flux sliding mode observer for Permanent Magnet Synchronous Motor
摘要
Abstract
To improve the performance of the torque precision for PMSM(Permanent Magnet Synchronous Motor)of railway vehicles, a novel sliding mode observer of active flux and a precise torque control method are proposed for a vector control system of PMSM. The concept of active flux is adopted and the mathematical model of Interior Permanent Magnet Synchro-nous Motor(IPMSM)has been established. The sliding mode observer of active flux is constructed in α-β stator coordinate frame, and it is observed active flux by applying sliding mode equivalent control methodology, then it realizes the real-time estimation of torque. The precise torque closed-loop control system is constituted combining with the torque command. The simulation results verify the feasibility and effectiveness of the method. The torque control precision of the PMSM can be improved, and the driving performance of railway PMSM vehicles is fulfilled and guaranteed. This method is not only applicable to IPMSM but to Surface-mounted Permanent Magnet Synchronous Motors(SPMSM)as well.关键词
