Abstract
A mathematical model is developed from partial differential equations for a hybrid structural model of a flexible, morphing wing. The hybrid model is made up of flexible plate representing the wing, and sets of membranes attached by control effectors to form a row of continuous flexible parts acting as leading edge slats and trailing edge flaps. This hybrid structure allows finer control on the shape of the wing while providing truly continuous trailing edge and leading edge surfaces. Since the control surface deflections change the shape of wing, producing a net moment at the wing root, the resulting heave motion results in the system becoming unstable. To control the system a recently developed adaptive control architecture using a mixed state and output feedback framework is implemented. The resulting controller provides the appropriate input to drive the system to produce a shape while enforcing strict performance guarantees.
