Abstract
Aiming at the problems of poor stability and low system accuracy in the vector control of permanent magnet synchronous linear motor (PMSLM), a vector control strategy for PMSLM based on model reference adaptive system (MRAS) is proposed. Improve the accuracy of speed and mover position estimation by selecting the appropriate adaptive law, and introduce a sliding mode control (SMC) strategy in the speed loop to optimize the vector control system. The simulation results shows that this method can effectively reduce the overshoot and chattering, and improve the stability of the system.
