Performance and stability properties of a smart double panel with decentralised active dampers

This paper presents a theoretical study of active damping on a double panel vibroacoustic system. The system consists of two vibrating panels, which are structurally and acoustically coupled via elastic mounts and the air in the cavity between the panels. The source panel is excited by an acoustic plane wave, while the radiating panel radiates sound into free-field. An array of sixteen structural actuators reacting against the two panels is located in the air cavity, in order to implement decentralised direct velocity feedback (DVFB) control loops. The aim is to generate active damping across the two panels so that the low frequency resonant sound transmission is reduced. It has been shown previously that collocated DVFB with idealized skyhook force actuators generates active damping on structures and is unconditionally stable. However, when reactive actuators are used, performance and stability of the system may be influenced by a feed-through effect via the mounting system or the air in the cavity. A mathematical model for the problem has been developed, which considers the fully coupled configuration. Simulations with various feedback arrangements have been performed, and the results discussed, focusing particularly on the control system performance and stability.
