A New Current Control Method for Torque Ripple Reduction on Brushless DC Motor

This paper presents a new current control method to reduce torque ripple of Brushless DC Motor during commutation. In the proposed control strategy, the current slopes of rising and decaying phase during commutation is equalized by the compensation voltage. By adding the compensation voltage for it to the current controller output, the reduced torque ripple can be obtained. The simulation and experimental results show that the proposed method reduces the torque and the current ripples significantly.
