Active damping of 'parasitic' vibration modes of a quartz sensor
Yann Meyer,Manuel Collet +1 more
TL;DR: In this article, an original control approach for active vibration stabilization of sensors made of quartz is introduced, which uses the piezoelectric framework of sensors, with respect to their operation, so as to damp 'parasitic' vibration modes.
