A Study of PID Direct Torque Control for Three-Phase Asynchronous Motor

Abstract

Three-phase asynchronous motors (are aslo called induction motors) are rugged, robust, and an integral part of many applications for most industries worldwide. The general type of the three-phase asynchronous motor, mostly used in industry, is the squirrel cage. The method introduced into this paper is called direct torque control (DTC), which utilizes the characteristic of a motor to produce a quick and robust response in inverters. The entire motor system is analyzed and simulated by Matlab and Simulink toolbox, where the PID direct torque controlled to approach is applied. Our main contributes to this paper is to compare the performance of induction motor, including three scenarios: without load, negative load and positive load by using PID direct torque control method. The simulation results show the effective of proposed control of induction motor with three scenarios.
