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 highly interconnected pr ....etc

Abstract:
The field oriented control emerged as an important approach for the control of AC machines, and continues to be explored and developed in the literature. The estimation of the rotor flux from the measurable variables was the only method used to implement the vector control of the induction machine. To replace the estimator based on the mathematical model of the system, which can lead to unintended errors due to uncertainties on the model and on the measures we use an appropriate observer.

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
with those of the DTC technique, generating the required voltage vectors under 0.9 input power factor
operations. The results d ....etc

Direct torque control (DTC) is one method used in variable frequency drives to control the torque (and thus finally the speed) of three-phase AC electric motors. This involves calculating an estimate of the motor's magnetic flux and torque based on the measured voltage and current of the motor. ....etc
