【Abstract】 Based on the mathematical model of permanent magnet motor for electric vehicle (EV), a drive system which consists of permanent magnet synchronous motor and three phase inverter for EV propulsion is presented. The performance on different control ways, magnetic field distribution and current wave is analyzed, the principle of control system is described. A novel control strategy is proposed to achieve regenerative braking of EV below the highest speed. The simulation and experimental results show that the drive system has satisfactory static and dynamic performance.更多还原
