摘要: 针对空中加油任务受油阶段受油机姿态稳定的需求,考虑受油机时变转动惯量、不确定转动惯量和风干扰的影响,提出了一种受油机指定时间姿态稳定控制策略。首先,建立了含时变转动惯量、内部不确定性和外部扰动下的受油机姿态动力学和运动学模型;其次,为了提高姿态稳定的快速性和确定性,使用指定时间稳定理论作为基础,设计了受油机姿态稳定鲁棒滑模控制器。与现有受油机控制策略相比,所提出的控制器优势在于可确保受油机在指定的时间内实现姿态稳定。同时,收敛时间显式存在于控制器参数中,设计者可根据任务需求和执行机构的物理限制,在允许的范围内自由调控。李雅普诺夫稳定性分析和数字仿真结果表明,该控制策略具有良好的控制性能,可实现指定时间稳定。

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.
