Effective flux observation and torque control for permanent magnet synchronous motor of railway vehicles
摘要
Abstract
The permanent-magnet synchronous traction motor mathematical model of active flux was established, and a nonsingular terminal-sliding-mode observer(NTSMO)based on effective flux and a precise torque con-trol method were proposed.An adaptive Luenberger-sliding mode observer was constructed inα-βcoordinate to estimate the stator resistance and q-axis inductance,which is regarded as the input to the active flux observ-er.The NTSMO of active flux was constructed inα-βstator coordinate frame,and active flux was observed by applying sliding mode equivalent control methodology,so as to realize the real-time estimation of torque.The torque closed-loop control system was constituted combining the torque command.The torque control precision of the driving system could be improved,and the driving performance of railway vehicles was fulfilled and guar-anteed.The method not only applies to surface-mounted permanent magnet synchronous motors(SPMSM),but also to interior permanent magnet synchronous motor(IPMSM).The simulation results verify the feasibility and effectiveness of the method.关键词
