All rights reserved. Tryck: Universitetsservice US AB Abstract Cooperation is increasingly being applied in the control of interconnected multi-agent systems, and it introduces many benefits. In particular, cooperation can improve the efficiency of many types of missions, and adds flexibility and robustness against external disturbances or unknown obstacles. This thesis investigates cooperative maneuvers for aerial vehicles autonomously landing on moving platforms, and how to safely and robustly perform such landings on a real system subject to a variety of disturbances and physical and computational constraints. Two specific examples are considered: the landing of a fixed-wing drone on top of a moving ground carriage; and the landing of a quadcopter on a boat. The maneuvers are executed in a cooperative manner where both vehicles are allowed to take actions to reach their common objective, while avoiding safety based spatial constraints. Applications of such systems can be found in, for example, autonomous deliveries, emergency landings, and search and rescue missions. Particular challenges of cooperative landing maneuvers include the heterogeneous and nonlinear dynamics, the coupled control, the sensitivity to disturbances, and the safety criticality of performing a high-velocity landing maneuver. -

Preface Dit verslag vormt het sluitstuk van mijn afstudeerstage bij het Koninklijk Nederlands Lucht- en Ruimtevaartcentrum (NLR). Niettegenstaande de individuele aard van de opdracht, heb ik kunnen rekenen op de ondersteuning van diverse personen. Hen ken ik bij deze graag een eervolle vermelding toe. Allereerst bedank ik mijn dagelijkse begeleider Jos Vankan voor het vertrouwen, de toewijding en het nodige geduld. Verder ben ik ook NLR- collega’s Wim Lammen, Jonathan Derei, Edward Rademaker en Oscar Kogenhop dankbaar voor hun inhoudelijke inbreng. Assia Haddou en Huy Tran bezorgden me niet alleen een warme ontvangst en vermakelijke momenten op kantoor, maar bleken ook een waardevol klankbord op momenten dat ik dat kon gebruiken. -
