Prof. Jean-Michel Coron, University of Paris VI, France Title: Finite-time stabilization Abstract: We present various results on the finite-time stabilization of control systems. This includes control systems in finite dimension (with an application to a quadcopter sliding on a plane) as well as control systems modeled by means of partial differential (1-D linear parabolic equations and a viscous Burgers' equation). |

Prof. Marius Tucsnak, University of Bordeaux, France Title: PDE systems describing the motion of solids in a viscous fluid: wellposedness, control and long-time behaviour Abstract: The study of systems describing the motion of rigid bodies in a fluid goes back to Euler and Kirchhoff, who considered the case of an ideal fluid subject undergoing a potential flow. The case of a single solid moving in a viscous incompressible fluid filling the whole space was considered much later, around 1980 by Weinberger and Serre. Welposedness issues for the case when the solid-fluid system is contained in a bounded container or/and of several moving bodies has been intensively studied since 2000. In this talk we first recall some of these wellposedness results . We next describe some associated control problems, aimed to provide a new approach to the understanding of the swimming of aquatic organisms. We finally describe some recent results concerning the long-time behaviour of solutions. |
