Abstract

In this paper, a new torque ripple compensator is proposed. The proposed torque ripple compensator utilizes only speed information, so it can be easily applied to an existing motor drive system by including the algorithm. The stability analysis is discussed. From the discussion, the proper gain selection method, which makes the compensator stable and fast convergent, is also presented. The experimental results are presented and show the torque ripple reduction capability of the proposed scheme
