Abstract

This work was focused on the implementation of an active noise control strategy for an acoustic-structural coupled enclosure using structural-based virtual sensors. A virtual sensing system was developed to estimate the broadband sound pressure at virtual interior locations in the enclosure based on structural vibration measurement of its flexible structure, instead of using acoustic sensors. Experiments on a panel-cavity test rig were performed and an active control system using the FX-LMS algorithm was used to minimize the noise at a virtual location based on accelerometer measurements. Experiment results showed that the broadband noise level at the virtual location was suppressed even when the actual system dynamics was perturbed from the original one, demonstrating the robustness of active noise control system.
