Modeling and simulation for the Permanent Magnet Linear Synchronous Motor based on space vector pulse width modulation

The space vector pulse width modulation (SVPWM) exhibits unique advantages when applied to Permanent Magnet Linear Synchronous Motor (PMLSM) control systems. In the paper, principle and algorithm of SVPWM and mathematical model of PMLSM are analyzed. Simulation model of Frequency Conversion Timing Control System is set up by MATLAB/SIMULINK for PMLSM based on SVPWM algorithm. This provided a good simulation platform to analyse the running characteristics of PMLSM. At the same time, we carried out the actual operation on the PMLSM based on SVPWM control strategy. The simulation results as well as experiment results show that the control system is accurate and practicable even though load disturbance and perturbation of parameters exist.
