Robust observer-based feedback for the incompressible Navier-Stokes equation

The stabilization of laminar flows on the base of linearizations and feedback controllers has been the subject of many recent theoretical and computational studies. However, the applicability of the standard approaches is limited due to the inherent fragility of observer based controllers with respect to model uncertainties. We analyse how an uncertainty in the Oseen-linearization of the Navier-Stokes equations affects the controller design and show that H-infinity robustness can handle these perturbations.
