Comparative Analysis of Various DTC Control Techniques on BLDC Motor for Electric Vehicle

Abstract

Electric vehicles are in the verge to getting advancement with boost from private operators and government policies. Brushless DC motor is electronically commuted motors which does not have brushes. BLDC motors have a higher efficiency compared to brush motor. With Sensor BLDC motors are facing problems of sensitive, and space. In sensor-less methods, control scheme needs to evaluate the operation by measuring by back EMF generated. In BLDC motor, direct torque control method can result in high torque ripples. In this paper, we have compared the conventional DTC with modified adaptive DTC with PID controller and further the results are compared with Artificial Neural Network based DTC method to check the operation of control system and its stability. The operation is justified and verified using MATLAB simulation.
