As main contribution we propose a fast and automated gradient-enriched machine learning control (gMLC) algorithm to learn feedback control laws. The framework alternates between explorative and exploitive gradient-based iterations, generalizing genet

The projected increase in air traffic volume has led to a renewed interest in drag reduction research to reduce aviation’s environmental impact. One solution is wall suction, which can effectively postpone the laminar-turbulent transition of a boun
