Particularly on large transport aircraft the first wing bending mode is significantly excited by atmospheric turbulence. Based on flight test data, it is shown that the related modal accelerations can be compensated very efficiently by feed-forward control. In order to increase the robustness of the control performance against plant uncertainties, an adaptive algorithm is designed for said feed-forward control. Moreover, the stability of the adaptation is analysed. Finally, the implementation of the proposed adaptive feed-forward controller is demonstrated in a wind tunnel experiment.
