Torque ripple reduction of switched reluctance motor using fuzzy control
Abstract
Purpose
Extensive efforts have been conducted on the improvement of torque ripple in switched reluctance motor (SRM) drive. The purpose of this paper is to estimate initial on time of pulse-width modulation (PWM) and turn-off angle using the motor speed and rotor angle by fuzzy logic.
Design/methodology/approach
A fuzzy logic control together with the PWM technique and turn-off angle are used to improve torque ripple and dynamic response.
Findings
After determining initial on time of PWM, the rise slope of phase current is increased.
Research limitations/implications
Future work will consider to increase the complex of the fuzzy control to adaptively tune parameters and achieve excellent results.
Practical implications
The experimental results of the proposed method are presented to show the effectiveness.
Originality/value
This paper achieves SRM control by one special PWM technique which is seldom studied.
