For permanent magnet brushless DC motor (BLDCM) in the square wave control of large torque ripple and current distortion and back EMF instability caused by the speed fluctuation problem, based on the analysis of BLDCM control mode, will be attributed to these problems in the control of current commutation and back EMF is not ideal square wave potential. Based on this, a vector control strategy for brushless DC motor vector control based on fuzzy control is proposed for electric vehicle BLDCM, this strategy uses fuzzy controller to adjust the speed error, thereby enhancing the performance of the speed control system; the use of vector control to replace the square wave control, thus overcoming the torque ripple and current distortion and back EMF is not stable. The experimental results show that the proposed control strategy can restrain the torque ripple and smooth the current and speed.
