Predictive Direct Torque Control for Flux and Torque Ripple Reduction [PDF]
IEEE Transactions on Industrial Electronics, 2010 In this paper, a prediction scheme is presented to diminish both the torque and flux ripples in a direct torque control (DTC) induction motor drive. In a discrete implementation of the classical DTC scheme, the time delay associated with data processing results in additional torque and flux ripples.
