Optimal Control of Systems Governed by the Navier Stokes Equations.

OPTIMIZATION AND APPLICATIONS SEMINAR // Optimal control, both open and closed loop, of systems describing flow phenomena still present diverse challenges due, in part, to their size, their nonlinearity and different flow regimes. These difficulties, in turn, have acted as a catalyst for the enhancement of control techniques for large systems of partial differential equations. - In this talk I shall present receding horizon techniques as well as model - reduction methods, based on proper orthogonal decomposition (POD) and approximate inertial manifolds concepts, and their impact on control of fluids.- For the numerial treatment of inequality constraints control or state variables semi-smooth Newton techniques will briefly be described.

Biographical Sketch:
Karl Kunisch received his Ph.D. in Mathematics from the Technical University of Graz, Austria, in 1978. He held positions at the Technical University of Graz and the Technical University of Berlin and he is now Professor of Mathematics at the University of Graz. He had temporary positions at Brown University, USA, The University of Oklahoma, USA, at Paris-Dauphine, and in INRIA Rocquen- court, France. Prof. Kunisch declined positions to the University of Erlangen (C3), the University of Munich(C4), and the University of Stuttgart(C4). He was the head of a Christian Doppler Laboratory for Parameter Estimation and Inverse Problems, published about 180 papers, and is on the editorial board of several journals. His research interests include Control and Optimization, Inverse Problems and Numerical Analysis.
