Abstract: To establish a reliable and convenient simulation model for permanent magnet linear synchronous motors (PMLSM), based on the analysis of the mathematical model of PMLSM, it sets up the simulation model for PMLSM and its control system by VisSim/ECD v8.0. The PID controller model with the position circle, speed circle and current circle were established. The simulation results by VisSim indicate that the position servo system is accurate and superior in tracking performance and robust performance. It can be applied to design and testify the rationality of other control strategies. This provides a new way of thinking for designing and debugging PMLSM servo system with high performance.
