Abstract :
The article study the direct torque control of permanent magnet synchronous in electric vehicle, analyze the torque ripple due to the limited number of voltage space vector. In view of it, current circuit is changed and vector is divided, six new voltage space vectors are used in the control system. Tanks of the new vectors, more vectors can be chosen, and more accurate control is obtained. The emulation result indicates the vector subdivision direct torque control can reduce torque ripple, polish up flux track and improve the performance of electric vehicle.
