A control design strategy is proposed based on control allocation for the longitudinal motion of aircraft with variable-span and variable-sweep morphing wing. A morphing aircraft can change its shape during the flight, which allows the morphing aircraft to carry out various missions efficiently. Morphing parameters can be considered as control inputs, and therefore the system has redundant control inputs. The dynamics of morphing aircraft is transformed into a state-dependent coefficient form and regarded as an over-actuated system by augmenting control input with morphing parameters. Control allocation is used to distribute the generated control input adequately. Control allocation solves the optimization problem to minimize the displacement of control input, which is designed separately with the controller. Numerical simulations are performed to demonstrate the effectiveness of the proposed controller.
