Flare control law design via multi-channel ℋ<inf>∞</inf> synthesis: Illustration on a freely available nonlinear aircraft benchmark

Abstract

Recent advances in the resolution of multi-channel ℋ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</sub> control problems via nonsmooth optimization are exploited in this paper to provide a novel design methodology in the challenging context of flare control systems optimization. More precisely, the objective is to control the vertical speed of an aircraft before touchdown while minimizing the impact of airspeed variations, windshear and ground effects. A realistic and rather complete aircraft benchmark (freely available from the SMAC project website <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> ) is also described in the paper.
