This work concerns the problem of gust load alleviation of a flexible aircraft by focusing on
Airbus's XRF1 aircraft concept, with a fully actuated wing. The aircraft is equipped with a …

The paper details the research and corresponding implementation and testing steps of the
FLEXOP demonstrator aircraft. Within the EU funded project an unmanned demonstrator …

The paper proposes a control design methodology for active flutter suppression for the
aeroservoelastic (ASE) aircraft of the European project FLEXOP. The aim of the controller is …

This paper presents an improved process for the modeling, model order reduction (MOR),
and control design of a flexible flying wing unmanned aerial vehicle based on the linear …

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 …

For many dynamical systems, it is required to actively control individual modes, especially
when these are lightly damped or even unstable. In order to achieve a maximum control …

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 …

The aim of this Paper is to propose a method for constructing worst-case disturbances to
analyze the performance of linear time-varying systems on a finite time horizon. This is …

This study performs an experimental and numerical investigation on the nonlinear
aeroelastic response of cantilever high-aspect-ratio beam-like wings with a ballast at their …

This paper proposes a nonlinear disturbance observer (NDO)–based sliding mode control
(SMC) method to the problem of stall flutter suppression for a revised Leishman–Beddoes (L …
