Position Sensorless Control of Switched Reluctance Generator for Wind Energy Conversion

Abstract
This paper presents a novel sensorless control system of switched reluctance generator (SRG) in order to reduce cost, simplify system structure and increase reliability. Considering nonlinear characteristics of SRG and robustness of sliding mode observer (SMO), sensorless control method of SRG based on SMO is proposed and analyzed. For wind energy conversion system (WECS), a voltage-source PWM inverter is used to make power output of SRG ....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

switched reluctance motor ppt

The switched reluctance motor (SRM) is a type of a stepper motor, an electric motor that runs by reluctance torque. Unlike common DC motor types, power is delivered to windings in the stator (case) rather than the rotor. This greatly simplifies mechanical design as power does not have to be delivered to a moving part, but it complicates the electrical design as some sort of switching system needs to be used to deliver power to the different windings. With modern electronic devices, precisely timed switching is not ....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 relat ....etc

This document presents a four-quadrant controller for switched reluctance motor (SRM) drives with optimal ignition and turning angles for each operating quadrant. Trigger angles are chosen to maximize the average torque produced by the motor, which requires optimizing the area of the power conversion loop. The four-quadrant SR controller developed with the chosen optimization criteria provides fast response in the engine as well as a rapid braking response. The underlying contribution of this work is the development and solution of an optimal c ....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 is added in a current regulated speed control loop.
