Aerodynamic parameters change when morphing aircraft performs the morphing process, thereby varying the aerodynamic characteristics of the aircraft. Flying stability and control accuracy may not be guaranteed by common methods. Taking the variable-sweep aircraft as research object, aiming at the uncertainty problems of nonlinear model of morphing aircraft in morphing process, this paper designs triaxial attitude control laws based on active disturbance rejection control (ADRC). The changes of aerodynamic characteristics while morphing and the strong coupling between different channels are treated as disturbances, and included in total disturbance of the whole system, which is cancelled by the means of extended state observer (ESO). The simulation result indicates that the proposed attitude control laws show great control effect for varying sweeps, with high control precision and strong robustness.
