Abstract

Switched Reluctance Motors are used for variable speed application at very high speed. In this motor the losses are less and efficiency is more because there are no windings on the rotor. But torque pulsations in SRM are relatively higher compared to other ac machines due to nonlinear inductance profile. Both, machine design and electronic control approaches have been used to minimize the torque ripples in SRM to achieve better performance of SRM drive system. The objective of this paper is to investigate performance of 6/4 switched reluctance motor with fuzzy logic controller with various converter topologies i.e. asymmetric converter, R-Dump converter, miller converter and modified power converter. The present work also concentrates on the modeling of SRM drive with fuzzy logic controller for SRM speed control by using MATLAB/Simulink environment. The fuzzy logic controller is designed using simulink toolbox.
