Compensation of torque ripple of brushless DC motor using feedforward method

Feedforwad 방법을 이용한 BLDC 모터의 토크리플 보상

In recent years, there has been a renewed interest in the BLDC motor as a research subject. In this paper we inspect sources of the torque ripple, which is one of the elements causing performance depreciation of BLDC motors. Based on the inspected sources of the torque ripple, feedforward compensation methods are proposed to reduce the size of torque ripple. The effectiveness of the proposed methods is verified with experiments.
