In order to control electric vehicle PMSM (Permanent Magnet Synchronous Motor) stably run in whole speed range, this paper designs a control algorithm combining linear interpolation look-up method MTPA (the Maximum Torque per Ampere) control and modulation hysteresis loop flux weakening control. So the purpose of stable control is achieved when the motor speed and the torque changed at any time during the operation. The algorithm uses flux weakening algorithm to compensate the instruction current of MTPA control, then correct the current vector trajectory and speed up the motor. Finally, the bench test and driving experiment on the electric vehicle shows that the algorithm can run steadily and achieve the desired goal.
