Mission
The ANVC LAB is dedicated to the study of active and semi-active control systems for noise and vibration mitigation. The LAB provides the equipment necessary to implement both feed-forward and feedback single-channel and multi-channel systems. The LAB is thus fully equipped with vibration sensors (accelerometers, piezoelectric patches, force gauge, laser vibrometer), acoustic sensors (microphones), mechanical actuators (shakers, coil-magnet seismic vibrometers, piezoelectric patches) and acoustic actuators (loudspeakers). Also, it offers the typical signal conditioning devices necessary to power and detects signals (voltage amplifiers, current amplifiers, low/high/band pass filters, etc). Finally, it provides a multi-channel system for the time-acquisition and frequency analysis of the measured signals and two digital boards for the implementation of real time multi-channel control systems.
