This compact course will enable students to apply state-of-the art methods of open- and closed-loop turbulence control targeting aerodynamic or aeroacoustic performance increases.
Focus is placed on strategies with a proven track-record in experiments. The lectures start with classical linear modeling and control. Then, key nonlinearities of turbulence are distilled in low-dimensional models and corresponding control design.
Finally, we describe recent breakthroughs with machine learning control (MLC) which explores and exploits nonlinear actuation mechanisms in an automated manner. MLC includes both control optimization in a running experiment as well as low-dimensional model identification.
All methods are first introduced for simple dynamical systems, which students can use as exercise, before being illustrated with recent experimental literature results.
