Abstract The German Aerospace Center (DLR) is currently developing an unmanned
experimental solar-powered fixed-wing high-altitude platform designed to be stationed in the …

The model-based flight control system design for a highly flexible flutter demonstrator,
developed in the European FLEXOP project, is presented. The flight control system includes …

Flutter is an aeroelastic phenomenon affecting flexible structures in a fluid flow and may lead
to unstable oscillations and to critical structural damage. This paper concerns the design of a …

The present thesis is the result of my work at the Institute of System Dynamics and Control at
the German Aerospace Center (DLR) in Oberpfaffenhofen, Germany. My thanks go to Prof …

This article presents a method for structured robust control design for systems with a mixture
of parametric and dynamic uncertainty. The proposed method alternates between an …

Abstract High Altitude Long Endurance (HALE) aircraft consist of extremely light-weight
structures in combination with a high wingspan and high aspect ratio. The combination of …

FLEXOP is a project within the European Union's Horizon 2020 framework which develops
methods for aeroelastic wing tailoring and active flutter suppression. The developed …

aircraft designs with respect to new materials and high aspect ratio wings demand for …

Flexible aircraft are particularly sensitive to wind disturbances. To prevent this drawback and
enable highly fuel-efficient aircraft design, the reduction of gust loads is an inevitable step to …

The dynamic behaviour, stability, and the effects of the aerodynamic drag of a large-
wingspan aircraft are mainly influenced by the structural flexibility and shape of the wings …
