Research on Permanent Magnet Linear Synchronous Motor Control System Simulation

Based on the analysis of mathematical models of PMLSM and theories of vector control, it puts forward control system modeling method, two control loops which are the inner current-loop and the outer speed-loop are used in Matlab/Simulink, permanent magnet linear synchronous motors mathematical model is also modeled by end effect and three phase asymmetric winding. The simulation results proved the affectivity of the system's model and verified its control calculation way, and it also provided sufficient theoretical basis for designing and adjusting in practical control system.
