A Review on Direct Torque Control for Induction Motor

The aim of this paper is to review the origin and developments of Direct Torque Control (DTC), an advanced control technique of induction motor drives yielding superior performance. The direct torque control is one of the excellent control strategies available for torque control of induction machine. It is considered as an alternative to Field Oriented Control (FOC) technique. The DTC is characterized by the absence of PI regulators, co-ordinate transformations, current regulators and pulse width modulated signal generators. DTC also allows a good torque control in steady state and transient operating conditions. The purpose of this study is to control the speed of 3-Phase Induction Motor with Artificial Neural Network (ANN) controller. The Artificial Neural Network Controller will be designed and must be tuned. This is about introducing the new ability of in estimating speed and controlling the 3phase Induction Motor. In this paper, a study of ANN Controller is used to control the speed of 3-Phase Induction Motor. The ANN Controller is programmed to control the speed of 3-Phase Induction Motor at certain speed level. Direct Torque Control (DTC) is one of the latest techniques to control the speed of motor.
