Instantaneous current profile control for flat torque of switched reluctance motors

Abstract

This paper presents a new instantaneous current control to obtain an instantaneously flat torque waveform with smaller torque ripples of switched reluctance motors (SRMs). The proposed current control is based on table lookup. By geometric insights for the machine and finite element method based analysis, ideal current profiles for the flat torque are generated. Some simulation results are presented to demonstrate the validity of the proposed control, which are verified by experiment. © 2008 Wiley Periodicals, Inc.
