The DEAL is here - What now?

An update to my 2020 talk and takes on the DEAL.

The DEAL - What is up and what does it mean

Robust Controller versus Numerical Model Uncertainties for Stabilization of Navier-Stokes Equations

We consider the stabilization of incompressible fluid flow using linearized and spatially discretized models. In order to potentially work in applications, the designed controller must stabilize the discrete model with a robustness margin that covers …

Convergence of Approximations to Riccati-based Boundary-feedback Stabilization of Laminar Flows

Riccati-based feedback is commonly applied for the stabilization of flows in theory and in simulations. Nonetheless, there are few attempts to show the convergence of numerically computed feedback gains to the feedback defined by the actual model. In …
