Title: Smart Boundary Control of VibroAcoustic and Elastodynamic Systems

Short description

The aim of the thesis is to propose passivity based control strategies for the acoustic or elastic wave attenuation at the output of 2D and 3D acoustic systems. A first approach will use a distributed dissipative port-Hamiltonian model of the system for the control synthesis. In a second instance, the derivation of a finite dimensional port-Hamiltonian approximation based on k- forms will be developed and used for the control design. In both cases, special attention will be given to the reduction/approximation scheme and the fact that the control will account for the structure of the distributed network of actuators/sensors. More specifically, the robustness of the controllers will be investigated with respect to the structured model error of the finite dimensional approximation of the infinite-dimensional port-Hamiltonian system.

An experimental set-up will be available to validate the developed control approaches.

Keywords: port-Hamiltonian systems, partial differential equations, passivity based control, acoustic systems.
