Simulation Study on Direct Torque Control of Induction Motor using Neural Network

Abstract DC motors were used in adjustable speed drives system in most of the industrial applications, due to the various disadvantages of DC motor drives system, AC motor drives has been replaced from last four decades, after the existence and availability of fast acting semiconductor devices. The methods used to control the torque using induction motor were found to be not as better as that of DC motor; However lot of research work is in progress to develop good response of torque in AC motor drives. In this paper the high performance implementation of induction motor control called as direct torque control (DTC) using neural network has been used to reduce torque ripple. Simulation work is carried using MATLAB/SIMULINK software based on PI controller and compared with the results obtained with neural network control.
