Vibration Reduction Control of Switched Reluctance Machine.

In this paper, a new vibration reduction control of the switched reluctance machine (SRM) is proposed, which takes into consideration the undesirable effects of the torque ripple. The control approach aims to reduce the variation of the sum of radial forces while optimizing the control parameters of the machine to achieve the torque ripple minimization. Thus, a reference current adapter is used in order to handle the tradeoff between the vibration reduction and the torque ripple reduction. It produces an auto-tuning reference current that limits the variation of the torque and of the total radial force. The effectiveness of the proposed control strategy is proved by simulation and experimental results. Comparisons with conventional control methods investigating vibrations, noise, and torque ripple are provided, which show the advantages of the control approach based on an auto-tuning reference current.
