Abstract

This paper presents an improved direct torque control scheme with space vector modulation techniques (DTC-SVM) for induction motors to eliminate the disadvantages of the traditional DTC-SVM scheme at low speed, speed step changing and torque step changing. Unlike the traditional DTC-SVM using PI controllers in the speed, flux and torque control loops, the improved DTC-SVM scheme uses Fuzzy-PI controllers in these control loops. Simulations with the deferent operating conditions for the presented DTC-SVM scheme and conventional DTC-SVM scheme are carried out in the Matlab/Simulink platform. According to the simulation results, the improved DTC-SVM scheme with Fuzzy-PI controllers produce better performances in terms of response, efficient of flux and speed regulations with dynamic load.
