Morphing capabilities allow for the design of a wing structure able to drastically change its external shape. The adaptive and flexible morphing wing is thus able to achieve high efficiency throughout the entire flight envelope reducing, for instance, consumption and pollution and improving aerodynamic performance. In order to achieve its potential, a morphing wing necessitates the development of an effective controller and, in particular, of an accurate feedback system able to provide a real-time reconstruction of the multitude of possible shapes achievable by the morphing wing. In developing a feedback system, successful results have been collected by recreating the displacement field of the wing structure from the actual measurements of the strains of the structure itself.
