Research on Linear Synchronous Motor Control System Based on Space Vector PWM

Introduction was made to the basic principle of space vector PWM.Aiming at the linear synchronous motor used in magnetic suspension train,a model of linear synchronous motor under the conditions of Matlab/Simulink was built up.This paper adopted space vector PWM method to construct linear synchronous motor control system which contained velocity and current control loops.The simu-lation results prove that the system is with good control characteristics.
