摘要: In this paper, a prediction scheme is presented to diminish both the torque and flux ripples in direct control (DTC) induction motor drive. discrete implementation of classical DTC scheme, time delay associated with data processing results additional ripples. This part can amount significant fraction overall ripple if hysteresis bands are comparable maximum variations one sampling interval. paper presents low computational complexity parameter sensitivity, standard scheme. The easily be extended compensate for multiple delays when frequency raised but computation remains unchanged. Experimental show diminishing effect on
