Torsional active-passive dampers on rotational machinery

Résumé

Recent hybrid control concepts, mixing active control with a fail-safe passive device, have drawn attractivity as they benefit from a theoretical hyperstability, ensuring very high stability margins. However, they have been experimentally tested until now only for the control of bending vibrations. The main purpose of this paper is to prove the performance of such systems also on torsional vibrations, with a specifically designed electromagnetic device, in order to contemplate the possibility to use them also for rotating machinery. As these control laws are model-free and require the adjustment of a few parameters related to the passive damper only, we demonstrate here their ease of integration for an application in rotating machines and we exhibit a direct experimental validation on an academic test bench. The latter which enables this experience despite the peculiarities of the rotation is therefore described, and the torsion reduction permitted by the hybrid control laws is assessed. A comparison between two of the newest hybrid control laws is also provided, proving the robustness and performance of these two hyperstable control laws. The main control parameters have been investigated and the performances are given through classical indicators but also in terms of energy consumption.
