This paper focuses on the dynamic model of aircraft with varying mass portion and attitude control during refueling process. By extending the 6-DOF nonlinear motion equations of fixed weight aircraft, the varying mass and inertia are taken into considering. By transforming the equations into affine-nonlinear form, an ADRC controller can be applied to control the attitude angle. After building up the controller, three refueling strategies are proposed to test it. Simulation results show that the model can reflect varying mass correctly, and the controller can suppress the influence and control attitude successfully. The ADRC controller compared with PID controller shows better performance under wind disturbance. Besides discussing the additional force caused by varying mass portion.
