Abstract: Considering the time-varying rotational inertia, uncertain rotational inertia and wind disturbance of the receiver aircraft, a predefined-time attitude stabilization control strategy for the receiver aircraft during the refueling phase in aerial refueling task is investigated in this paper. First, attitude dynamic model and kinematic models of the receiver aircraft with time-varying rotational inertia, internal uncertainty, and external disturbance are established. Second, to improve the rapidity of attitude stabilization control, a robust sliding-mode attitude stabilization controller is designed on the basis of the predefined-time stability theory. In comparison to the existing control strategies for the receiver aircraft, the proposed controller can ensure that receiver's attitude be stabilized in the predefined time, and the convergence time can be explicitly defined in advance within the allowable range through controller parameters according to the control demand and actuator physical limits. Lyapunov stability analysis and numerical simulation results manifest that the proposed control strategy exhibits excellent performance of attitude stabilization.
