Simulation and analysis of a PMLSM control system based on SVPWM

This paper aims to develop a permanent magnet synchronous motor (PMLSM) control system based on space vector pulse width modulation (SVPWM) and analyzes its control effectiveness. Mathematical simulation models of PMLSM and SVPWM are firstly presented and established in Matlab/Simulink. An open-loop simulating control system and a field-oriented vector control (VC) based close-loop system are then built, and their control effectiveness is analyzed. To overcome the shortages of great overshooting and poor dynamic response of the traditional VC and improve the precision of position, a position-tracking control strategy is proposed and simulated. Analytical results indicate that the proposed strategy can improve the stability and precision of the PMLSM control system.
