Feedback Control of Turbulent Shear Flows by Genetic Programming

Understand

Turbulent shear flows have triggered fundamental research in nonlinear dynamics, like transition scenarios, pattern formation and dynamical modeling.

• In particular, the control of nonlinear dynamics is subject of research since decades.
• In this publication, actuated turbulent shear flows serve as test-bed for a nonlinear feedback control strategy which can optimize an arbitrary cost function in an automatic self-learning manner.
• This is facilitated by genetic programming providing an analytically treatable control law.
