Torque ripple reduction of switched reluctance motor using fuzzy control

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.
