Modélisation et contrôle actif des vibrations d'une structure intelligente

In this paper, we consider the problem of modeling a smart structure in the finite element framework thanks to 2D-3D elements linking. The concerned structures are plate like and equipped with several piezoelectric patches, discretely distributed on one face of the plate. Some of them are used as sensors and the others are used as actuators. The aim is to obtain a state-space form model of the dynamical input-output behavior. This model is used for active vibration control purposes.
