[Contrôlabilité exacte d'un corps piézo-électrique]
On considère un corps constitué d'un matériau dont la loi constitutive introduit un couplage élastique-électrique. On montre que, sans faire aucune hypothèse géométrique, l'application de deux contrôles agissant sur la totalité de la frontière (un contrôle élastique et un contrôle électrique) permet de contrôler le système en temps fini.
In this Note we study the exact controllability of a three-dimensional body made of a material whose constitutive law introduces an elasticity-electricity coupling. We show that, without any geometrical assumption, two controls (the elastic and the electric controls) acting on the whole boundary drive the system to rest in finite time.
