This paper presents a longitudinal morphing-aided maneuver control model of an aircraft which could change wing span and change sweep angle, and solved the morphing aircraft control problem of parameter uncertainty and external disturbance by a robust composite control strategy with nonlinear control allocation. Based on DATCOM simulation software and nonlinear least square interpolation, the aerodynamic model is obtained, and established the longitudinal morphing-aided maneuver control model of morphing aircraft. To ensure the maneuverability of the morphing aircraft, a nominal controller which could converge in finite time is designed. The integral sliding mode disturbance observer with super screw control is designed to eliminate the tremor, and the uncertainties and external disturbances are observed and compensated. Then the obtained control signals are assigned to each control inputs through nonlinear control allocation. The simulation result show the effectiveness of the scheme, and prove that the aircraft has good tracking performance by independently changing the shape to assist the traditional control surface.
