Abstract
Galerkin models for 3D-turbulent boundary layers usually are too complex to be successfully incorporated into model based control strategies. Limiting the frequency spectrum of the ensemble data offers a possibility to reduce the model size and still map the control-relevant dynamics into the reduced-order model. An adaptation of the standard POD-Galerkin procedure is proposed using the example of a turbulent boundary layer, which is actuated by a periodic volume force. A closed-loop simulation shows an exemplary application of such a reduced order model in a model based control setup.
