TLDR
A new strategy of PWM current control for smooth operation of the drive is presented, which includes a current control strategy during commutation when torque ripple minimization is of utmost importance.
Abstract: 
Higher torque ripple is one of the few drawbacks of switched reluctance motor (SRM) drives, which otherwise possess excellent characteristics for applications in many commercial drives. This paper begins with an extensive review of torque ripple reduction methods that appear in the literature and then presents a new strategy of PWM current control for smooth operation of the drive. This method includes a current control strategy during commutation when torque ripple minimization is of utmost importance. >

Torque ripple reduction of switched reluctance motors by phase current optimal profiling

D.S. Schramm, +2 more
TL;DR: In this paper, the position-phase current profile for current feeding a four-phase, 4 kW switched reluctance motor is optimized to minimize both the average and peak current and hence improves the dynamic performance of the novel six-switch, current-fed, 4-kW, 40 kHz IGBT inverter.

An experimental study on composite control of switched reluctance motors

D.G. Taylor
- 01 Feb 1991 - 
TL;DR: In this paper, a nonlinear dynamic model is developed and decomposed into separate slow and fast subsystems, and a feedback control is designed so that, whenever the fast subsystem is at equilibrium, the dynamics of the slow subsystem are input-output equivalent to a second-order transfer function.
