Stability and Controllability of the Electromagneto-Elastic SystemS. NicaiseUniversité de Valenciennes et du Hainaut Cambrésis,MACS, Institut des Sciences et Techniques de Valenciennes, F-59313 -- Valenciennes Cedex 9 -- FRANCE Abstract: We consider the stabilization of the nonstationary electromagneto-elastic system in a bounded region with a Lipschitz boundary by means of nonlinear boundary feedbacks. This requires the validity of some stability estimate in the linear case that may be checked in some particular situations. As a consequence we get an explicit decay rate of the energy for appropriate feedbacks. By Russell's principle we further get some exact controllability results. Keywords: elasticity system; Maxwell's system; stability; nonlinear feedbacks. Classification (MSC2000): 93D15, 93B05, 93C20. Full text of the article:
