DIRECT TORQUE CONTROL OF INDUCTION MOTOR USING ARTIFICIAL NEURAL NETWORK


INTRODUCTION
A neural network is a powerful data modeling tool that is able to capture and represent complex input/output relationships . In the broader sense, a neural network is a collection of mathematical models that emulate some of the observed properties of biological nervous systems and draw on the analogies of adaptive biological learning. It is composed of a large number of hi ....etc

Abstract:
During a long time, permanent magnet synchronous motor (PMSM) were only reserved for some
specific applications, however, recently, these machines are becoming more used due to the powerful magnetic
characteristic of the rare earth, being used in different areas. Recently several researchers have proposed
implementations combining the use of permanent magnet synchronous motor with the direct torque control (DTC)
technique offering a quick and precise control. The present work combines these techniques and it proposes th ....etc

DIRECT TORQUE CONTROL FOR MATRIX CONVERTER-FED THREE PHASE INDUCTION MOTOR WITH HYBRID PSO
ABSTRACT
Direct Torque Control (DTC) for Induction Motors using Matrix Converters is a high performance motor
control scheme with fast torque and flux responses. This paper presents a new control scheme based on
hybrid particle swarm optimization (HPSO). The main advantages of the matrix converter are combines

Abstract
This paper introduces a sensorless nonlinear control
scheme for controlling the speed of a permanent magnet
synchronous motor (PMSM) driving an unknown load torque.
The states of the motor and disturbance torque are estimated via
an extended nonlinear observer avoiding the use of mechanical
sensors. The control strategy is an exact feedback linearization
law, with trajectory tracking evaluated on estimated values
of the PMSM states and the disturbance torque. The system
performance is evaluated by simulations.

Abstract

Direct Torque Control (DTC) is quite different from vector control and has several advantages compared to vector control. This paper presents intelligent control scheme together with conventional control scheme by fuzzy logic approach, to overcome the problems with uncertainties in the structure encountered with classical model based design. To adjust the speed of the direct torque control of induction motor drive, a fuzzy state feedback controller is pro ....etc
