Limites et outils d'optimisation du contrôle acoustique actif

Abstract : This dissertation introduces a set of scientific works aiming at widening the scope and the performances of Active Noise Control. Physical constraints, such as the causality constraint of real-time algorithms or the shortening of wavelength as frequency increases, are discussed, and optimization tools are suggested for the design of better-performing practical set-ups. This dissertation successively considers the widening of the actively controled area, the control of more complex sounds, the formulation of better-posed problems and the control of acoustic variables that cannot be directly measured. Beyond the introduction of research work carried at the CNRS-Laboratoire de Mécanique et d?Acoustique, this dissertation aims at showing that Active Noise Control is not a mere implementation of theoretical results from automatics and acoustics but a hot research topic in acoustics.
