    摘要:

    本文针对多高超声速滑翔飞行器在复杂终端约束下的协同制导问题,提出了一种融合单体预测校正与群体分布式一致性的协同制导方法。其核心创新在于构建了一个双层协同制导架构:在单体制导层,通过结合最优制导与预测校正策略,实现了对终端位置、速度倾角、方位角及攻击时间的高精度一体化控制;在群体协同层,设计了以待飞时间为协调变量的分布式协同框架,并综合考虑飞行器弹道特性与能力约束,提出了基于一致性协议与均值法的协调变量自主更新算法,从而实现了多飞行器在无中心节点条件下的自主时间同步与弹道协同。仿真验证表明,该方法能够在强时空约束下,使飞行器集群同时满足终端多约束并实现高精度时间与空间协同。

    Abstract:

    This paper addresses the cooperative guidance problem for multiple hypersonic glide vehicles under complex terminal constraints and proposes a cooperative guidance method that integrates individual prediction-correction and group distributed consensus. The core innovation lies in constructing a two-layer cooperative guidance architecture. At the individual guidance layer, by combining optimal guidance with a prediction-correction strategy, high-precision integrated control over terminal position, flight path angle, azimuth angle, and impact time is achieved. At the group cooperation layer, a distributed cooperative framework with time-to-go as the coordination variable is designed. Considering the vehicles" trajectory characteristics and capability constraints, a coordination variable autonomous update algorithm based on consensus protocol and the mean method is proposed, thereby enabling autonomous time synchronization and trajectory coordination for multiple vehicles under leaderless conditions. Simulation results demonstrate that the proposed method can ensure the vehicle cluster simultaneously satisfies multiple terminal constraints and achieves high-precision time and space coordination under stringent spatiotemporal constraints.
