A novel torque ripple reduction strategy for direct torque control of the induction maotor

Telford, D. and Dunnigan, M. and Williams, B.W. (2001) A novel torque ripple reduction strategy for direct torque control of the induction maotor. IEEE Transactions on Industrial Electronics, 48 (4). pp. 867-870. ISSN 0278-0046

Abstract

This letter presents a simple duty-cycle control scheme for the direct torque control of an induction motor. The scheme reduces torque ripple, controls the average output torque, and reduces the variation in switching frequency. The effectiveness of the proposed technique is demonstrated through experimental results.
