FUZZY LOGIC CONTROL OF A SWITCHED RELUCTANCE MOTOR



Abstract

This paper presents the use of fuzzy logic control (FLC) for switched reluctance motor (SRM) speed. The FLC performs a PI-like control strategy, giving the current reference variation
based on speed error and its change. The performance of the drive system was evaluated through digital simulations through the toolbox Simulink of Matlab program.

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

Abstract
Bearingless switched reluctance motors, whichcan control rotor radial positions with magnetic force, havebeen proposed. Bearingless switched reluctance motors havecombined characteristics of switched reluctance motors andmagnetic bearings. Production of radial force for rotor shaftmagnetic suspension is explained with differential stator windings.Mathematical relations between motor currents and radial forceare derived by considering cross coupling and fringing fluxes.Theoretical relationships are verified with experimental re ....etc

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 SR ....etc

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
