落角与视场约束制导控制一体化策略

针对考虑视场(FOV)约束和落角约束的高超声速飞行器高精度打击问题，提出一种基于自适应动态规划(ADP)的新型制导控制一体化(IGC)策略。首先设计一种融合视场角与落角约束的视场角指令，在视场角精确跟踪的同时实现精确命中并满足两种约束，从而将约束问题转化为跟踪问题；然后，借助干扰观测技术估计制导控制一体化模型中不确定性并引入到性能指标设计中，又同时将视场角约束与落角约束考虑进去，设计基于自适应动态规划的制导控制一体化方法。利用ADP的强化学习思想求解出最优控制策略，既保证高超声速飞行器的精准打击，又满足视场角约束与落角约束，而且兼顾了对不确定性的鲁棒性。仿真结果验证了本文所提方法的有效性与优势。

Integrated Guidance and Control Strategy with Constraints of Impact Angle and Field of View

A novel integrated guidance and control (IGC) strategy based on adaptive dynamic programming (ADP) is proposed for high precision strike of hypersonic vehicles with the constraints of field of view (FOV) and impact angle. Firstly, a FOV command integrating the FOV angle and impact angle constraints is designed to achieve accurate hit and satisfy two constraints while tracking FOV angle accurately, thus transforming the constraint problem into a tracking problem. Then, the adaptive dynamic programming guidance and control integration method is designed with the help of adaptive disturbance observer technology. The guidance control state quantity and uncertainty are introduced into the performance index, and the FOV constraint and impact angle constraint are taken into account. The optimal control strategy is solved by using the reinforcement learning idea of ADP, which not only ensures the accurate strike of the hypersonic vehicle, but also satisfies FOV and impact angle constraints, and takes into account the robustness to uncertainty. The simulation results verify the effectiveness and advantages of the proposed method.
