Abstract :
A principal challenge in the use of empirical proper orthogonal decomposition (POD) Galerkin models for feedback control design in fluid flow systems is their typical fragility and poor dynamic envelope. Closed loop performance and optimized sensor(s) location are significantly improved by use of interpolated POD modes from a succession of low dimensional models from sections of a controlled transient manifold. This strategy is demonstrated in the benchmark of stabilization of the wake flow behind a circular cylinder.
