Abstract: The Direct Torque Control (DTC) is well known as an effective control technique for high performance drives in a wide variety of industrial applications and conventional DTC technique uses two constant reference value: torque and stator flux.In this paper, fuzzy logic based stator flux optimization technique for DTC drives that has been proposed.The proposed fuzzy logic based stator flux optimizer self-regulates the stator flux reference using induction motor load situation without need of any motor parameters.Simulation studies have been carried out with Matlab/Simulink® to compare the proposed system behaviors at vary load conditions.Simulation results show that the performance of the proposed DTC technique has been improved and especially at low-load conditions torque ripple are greatly reduced with respect to the conventional DTC.
