Abstract :
Two adaptive feedback control methods, a new adaptive integral controller used to control plants with output saturation and dead-time and the well-known extremum seeking feedback are employed to control detached flows. For the experimental validation, conducted in a wind tunnel, two different flow configurations, a backward-facing step and a diffuser, are used. These experiments confirm that the presented control strategies can be used successfully to manipulate a detached flow and thus to reduce negative concomitant effects.
