SUMMARY:Séminaire d'Hugo Parada (IECL)
DESCRIPTION:Titre : Rapid stabilization of PDEs with disturbances.\n\nRés
 umé : In this talk\, we analyze the rapid stabilization of two classes of
  partial differential equations affected by unknown localized disturbances
 . We first consider an unstable wave equation with a boundary disturbance\
 , where a feedback law acting at the same point as the perturbation guaran
 tees exponential decay of the energy for any prescribed rate. Then\, we st
 udy a parabolic model with an interior disturbance and design a localized 
 feedback based on spectral inequalities and Lyapunov techniques. In both c
 ases\, the inclusion of the multivalued sign operator provides robustness 
 with respect to the unknown disturbance. The well-posedness of the closed-
 loop system is established using the theory of maximal monotone operators.
  This talk is based on joint works with A. Huerta\, P. Guzmán\, and C. Ca
 lle.\n\nBio : Hugo Parada Ríos is a postdoctoral researcher in Mathematic
 s at Inria Nancy\, within the SPHINX team\, affiliated with the Institut 
 Élie Cartan de Lorraine\, working with A. Duca and R. Buffe. He previousl
 y held a postdoctoral position at the Institut de Mathématiques de Toulou
 se\, supervised by F. Boyer.\nHe completed his Ph.D. in Mathematics at the
  Laboratoire Jean Kuntzmann (Université Grenoble Alpes) under the supervi
 sion of E. Crépeau and C. Prieur\, and obtained his M.Sc. in Mathematics 
 at the Universidad Técnica Federico Santa María (Chile)\, supervised by 
 E. Cerpa and P. Guzmán. His research interests include the stability and 
 controllability properties of coupled PDEs with a focus on network structu
 res\, the stabilization of systems under constraints such as saturation\, 
 delays\, or perturbations\, and\, more recently\, the development of numer
 ical methods for kinetic and plasma physics models.\n\nLien teams :\nhttps
