TL;DR: Results from this study demonstrate the importance of including aeroelastic coupling in modeling the structural acoustic response of panels for interior noise control on modern aircraft and demonstrate that for future analysis of robust stability and performance, variations in the plant dynamics due to variations in flow conditions must be considered.

TL;DR: In this article, the authors investigated the effects of variations in external fluid convection velocity on power flow from an elastic plate coupled to a reverberant acoustic enclosure and subjected to convected fluid loading.

TL;DR: In this article, a coupled feedback model of the reverberant sound field including in bandwidth transducers is developed to capture accurately the phase characteristics of the system response, particularly at low-frequencies which dominate closed-loop system performance and stability.

TL;DR: In this article, the authors investigated the active control of panel flutter with piezoelectric transducers and including linearized potential flow aerodynamics, which was accomplished by approximating the aerodynamic generalized forces with infinite impulse response filters.

TL;DR: In this article, a convected fluid loaded plate, backed by a reverberant acoustic cavity, is modeled using Galerkin's method while the aerodynamic forces on the plate are approximated with a singular value decomposition method.
