In this paper, a modified fuzzy DTC of dual three phase induction machine (SPIM) is presented. The SPIM has a dual three phase windings spatially shifted by sixty electrical degree. In this work, a fuzzy controller is used instead a conventional three level hysteresis torque comparator to minimize the torque ripple. Besides, a modification in the switching table is presented. The performances of the proposed control schemes are evaluated and compared by simulation in terms of flux and torque
