Self-tuning Fuzzy PI scheme for DTC Induction Motor drive

In this paper, a robust self-tuning fuzzy speed controller for direct torque control using space vector modulation (SVM) technique is proposed for the high performance drives of induction motor. The design of robust self-tuning fuzzy speed controller greatly affects the performance of Induction Motor (IM) fed with a Voltage Source Inverter (VSI). The performance of the proposed self-tuning Fuzzy PI controller is compared with the corresponding fuzzy logic controller and PI controller. The performance index based on speed error is assigned to provide a numerical comparison among different controllers. When compared with other methods, the torque ripples are reduced remarkably with the proposed method. Simulation results verify the validity of the proposed method.
