Approximation Methods for Control of Structural Acoustics Models with Piezoceramic Actuators
The active control of acoustic pressure in a 2-D cavity with a flexible boundary (a beam) is considered. Specifically, this control is implemented via piezoceramic patches on the beam which produceExpand

Modeling and Control of Acoustic Structure Interaction Problems Via Piezoceramic Actuators: 2-D Numerical Examples
Abstract : The modeling and active control of acoustic pressure in a 2-D cavity with a flexible boundary (a beam) is considered. Control is implemented in the model via piezoceramic patches on theExpand
Mechanisms of active control in cylindrical fuselage structures
This paper summarizes ongoing efforts to understand and exploit active control techniques for low frequency noise suppression in aerospace applications. Analytical models are utilized in an effort toExpand
Aircraft Morphing program
In the last decade smart technologies have become enablers that cut across traditional boundaries in materials science and engineering. Here we define smart to mean embedded actuation, sensing, andExpand
Experimental Confirmation of a PDE-Based Approach to Design of Feedback Controls
Issues regarding the experimental implementation of PDE-based controllers are discussed in this work. While the motivating application involves the reduction of vibration levels for a circular plateExpand
Approximation methods for control of acoustic/structure models with piezoceramic actuators
Abstract : The active control of acoustic pressure in a two dimensional cavity with a flexible boundary (a beam) is considered. Specifically, this control is implemented via piezoceramic patches onExpand
Sound Transmission through a Cylindrical Sandwich Shell with Honeycomb Core
Sound transmission through an infinite cylindrical sandwich shell is studied in the context of the transmission of airborne sound into aircraft interiors. The cylindrical shell is immersed in fluidExpand
Active control of sound transmission/radiation from elastic plates by vibration inputs, II: Experiments
Actively controlled harmonic force inputs were applied experimentally to reduce the sound transmitted through an elastic circular plate. The control implementation used a time domain least meanExpand
