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.

ABSTRACT

This paper presents a scheme for designing a kind of wireless charging system aimed to provide power transmission for personal mobile devices such as cell phone. This scheme consists of three parts: wireless power transmission design, wireless signal transmission design and charging manage design. A circular array consisting of some antenna elements is employed in the scheme as transmit access of power and signal. In the supposed indoor condition, the transfer efficiency can up to 66%. The charging manage adopt a close-loop optimal ....etc

Introduction Switched reluctance motor (SRM) drives are simpler in construction compared to induction and synchronous types of machine. Their combination with power electronic controllers may yield an economical solution. The switched reluctance motor with passive rotor has a simple construction, but the solution of its mathematical model is rela ....etc

The Switched Reluctance Generator for Wind Power Conversion

The use of wind energy has become increasingly important as a renewable energy source, so there is an increasing interest in exploiting it using a Switched Reluctance Machine (SRM).

Introduction

In the last decades, the SRM serves as an important alternative in various applications both within the industrial and domestic markets, as a motor showing good mechanical reliability, high torque-volume ratio and high efficiency,and it is of low cost.Eventhough SRM is easy to build ....etc

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

ASTN (Automatic Switched Transport Network) allows traffic paths to be set up through a switched network automatically. The term ASTN replaces the term ASON (Automatically Switched Optical Network) and is often used interchangeably with GMPLS (Generalized MPLS). This is not completely correct as GMPLS is a family of protocols, but ASON/ASTN is an optical/transport network architecture. The requirements of the ASON/ASTN architecture can be satisfied using GMPLS protocols developed by the IETF or by GMPLS protocols that have been modified by the ....etc
