Abstract :
This paper extends earlier results on (optimal) control of nominally stable models in computational fluid dynamics by means of reduced-order models on state-space form. We consider stabilization of a computational fluid dynamics model of an unstable system. A stabilizing controller is found based on optimal control design for the reduced-order model and then applied to the full model, where it is shown through simulations to stabilize the system
