A bio-inspired gust rejection mechanism based on structural inputs is proposed. A force feedback controller is used to anticipate the onset of rigid body dynamics due to gust perturbations. Strain sensors are used to provide a measure of the forces applied to the aircraft wing and to the aircraft rigid body. These sensors are placed at the root of the aircraft and are mounted on a rigid plate for maximal output. The strain generated is then used in a feedback controller at different proportional gains. The results using strain feedback showed to be better when compared to a classical attitude controller implementation. A model for the aileron dynamics was also obtained using the VICON motion capture system. Attitude regulation control was therefore enhanced using wing load sensing proprioceptive wings in a feedback loop.
