lt is well established that the implementation of conventional DTC drive consisting of hysteresis-based torque controller suffers from high torque ripple and variation in switching frequency problems. One of the many approaches to tackle this problem is by introducing a non-hysteresis-based torque controller. This paper presents the simulation and analysis of a proposed fuzzy PI-based torque controller for DTC of induction motor drives. Comparisons and analysis between the proposed controller and the hysteresis- and PI -based controllers are presented. The results show that the proposed controller managed to reduce the torque ripple and produce a constant device switching frequency.
