摘 要：Space Vector Pulse Width Modulation (SVPWM) technique is one of the best method of PWM variable frequency drive and make the AC motor achieving the performance as good as DC motor.Permanent Magnet Synchronous Motor (PMSM) has many advantages of small volume,steady operation,high energy efficiency,large output torque,etc.To solve the problems of auto environment and energy sources,study on Pure Electric Vehicles (PEV) driven by PMSM based on SVPWM is an important research direction and has the practical value.On the basis of analyzing the basic models of SVPWM,PMSM and PEV,simulation model of PMSM Control System for PEV can be constructed.The results of the simulation show that the control system has super performance and meet the request of system.
