中文摘要： 软管式自主空中加油在军用和民用上有着十分重要的意义。在软管式自主空中加油对接过程中，头波效应不仅对飞行控制安全带来很大影响，而且还严重影响对接成功率。该效应下，对接控制问题可描述为：在复杂扰动下，慢动态受限系统精确跟踪快动态目标的问题。针对该问题，本项目主要从建模、可对接性和控制三个方面进行研究。首先，本项目研究面向控制的自主空中加油对接模型，其中头波效应对锥套受力的定量模型属于本项目的模型创新。为保证可靠对接，本项目进一步研究可对接性（Dockability）和可对接裕度。这两个概念为本项目的概念创新，它们将为对接初始位置选择和安全决策提供帮助。在以上基础上，研究自主空中加油可靠的对接控制，其中迭代学习控制+反馈 方法为本项目的方法创新。该方法拟用来解决以上提到的对接控制问题。为了验证设计的有效性，本项目最后进行仿真验证，包括数字仿真与自驾仪在环的半物理仿真。

英文摘要： Probe & drogue autonomous aerial refueling plays a critical role in the military and civil fields. During docking, the bow wave effect on the drogue will not only cause serious safety problems, but also reduce the docking success rate heavily. Under the bow wave effect, the docking control problem can be formulated to be a precision control problem that, in presence of complex disturbances, a restricted and slow dynamical system tracks a fast dynamical target. For this problem, this project will study it mainly from modeling, dockability and control. First, this project will study the control-oriented docking modeling, where the model of bow wave effect on the drogue is one of our contributions. For the reliable docking, this project will study the dockability and the degree of dockability. The two new conceptions are another contribution. They will help to choose a proper initial docking control position and make a safety decision. Based on the previous studies, this project will further study reliable docking control, where the iterative learning control + feedback method for docking is also a contribution. Iterative learning control is used to handle the precision control problem mentioned above. Finally, to demonstrate the effectiveness of our design, simulation will be implemented, including both numerical simulations and autopilot-in-the-loop simulations.
