Torque Ripple Minimization Of Switched Reluctance Machine
Using Genetic Algorithm

A major problem of Switched Reluctance Motors (SRM) is the Torque ripple, which causes undesirable acoustic noise and vibration. saliency of the stator and rotor is the main cause for this. This article describes an algorithm for reducing the torque dip on the basis of Genetic Algorithm (GA), thereby reducing the associated torque ripple.

Torque Ripple Minimization in a Switched
Reluctance Drive by Neuro-fuzzy
Compensation

Simple power electronic drive circuit and fault tolerance of converter are specific advantages of SRM drives, but excessive torque ripple has limited its use to special applications. A new method for shaping the motor currents so that the ripple can be reduced is presented by this paper. Here, a compensating signal is added to the output of a PI
controller. This i ....etc

Mustapha MESSAOUDI, Habib KRAIEM, Mouna BEN HAMED, Lassaad SBITA and Mohamed Naceur ABDELKRIM

Abstract
In this paper, the classical Direct Torque Control (DTC) of Induction Motor (IM) using an open loop pure integration suffers from the well-known problems of integration especially in the low speed operation range is detailed. To tackle this problem, the IM variables and parameters estimation is pe ....etc

Introduction
Preface To SWARAJ
Punjab, the bread basket of India, the land with 50376 sq. Km is situated in Northern part of India. It is agriculturally Indiaâ„¢s most advanced and most prosperous state. Punjab Tractors limited was promoted by PSIDC as one of its projects in 1970 for the manufacturing of agricultural tractors. Since, this gave independence to country from import of tractors, so brand name SWARAJ, total independence was given.

SWARAJ tractors conceived in 1965 by a team of dedicated engineers a ....etc

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

WHAT IS DTC ?
 Direct torque control is known to produce quick and robust response in AC drive system.
 Direct Torque Control describes the way in which the control of torque and speed are directly based on the electromagnetic state of the motor.

A special type of brushless motor is called a limited-angle torquer (LAT). LATs are constrained to produce torque through a rotation angle of less than 180 degree, But they are widely used to operate servovalves, direct laser mirrors, position missile-guidance radar antennas, open shutters for heat-seeking sensors, and power other systems that rotate through small angles.

The rotor in a limited-angle torquer carries field magnets, and the stator supports armature windings (similar to the construction of conventional brushless motors). LATs, ....etc
