用深度神经网络实现无人机群在有敌对干扰下的稳定编队运输
Deep Neural Network-Based Aerial Transport in the Presence of Cooperative and Uncooperative UAS
- 构建分层通信图,动态调整权重引导无人机群移动
- 即使部分无人机不配合,系统仍能保持局部收敛与整体稳定
- 适合需要高鲁棒性的无人机协同任务场景
我们提出一种基于深度神经网络(DNN)的分布式无人机群运输框架,适用于在 $\mathbb{R}^n$ 空间中运行的无人航空系统(UAS)。该框架通过初始编队构建分层互连通信图,利用前向调度机制分配随时间变化的通信权重,引导团队从初始状态到达最终配置,并确保多智能体运输动态的稳定性和收敛性。系统设计具有抗干扰能力,可应对不遵守协议的非合作无人机:保持固定前馈拓扑,实时剔除与非合作个体的连接,维持合作个体间的凸形前馈指导关系,并通过稀疏线性关系计算全局目标点。目标区域由 $N$ 个抽象点定义,作为最终期望位置,实现覆盖最优的同时降低计算开销并保障性能。大量仿真表明,在完全协作下,所有无人机均快速收敛至目标区域,边界余量达10%;在部分协作且存在非合作个体时,合作个体仍保持高收敛性,性能退化仅局限在扰动附近,体现良好的弹性与可扩展性。结果验证了前向权重调度、分层师徒协调与实时DNN重构能有效实现真实故障场景下的鲁棒、可证明稳定的无人机群运输。
原文摘要 · Abstract (English)
We present a resilient deep neural network (DNN) framework for decentralized transport and coverage using uncrewed aerial systems (UAS) operating in $\mathbb{R}^n$. The proposed DNN-based mass-transport architecture constructs a layered inter-UAS communication graph from an initial formation, assigns time-varying communication weights through a forward scheduling mechanism that guides the team from the initial to the final configuration, and ensures stability and convergence of the resulting multi-agent transport dynamics. The framework is explicitly designed to remain robust in the presence of uncooperative agents that deviate from or refuse to follow the prescribed protocol. Our method preserves a fixed feed-forward topology but dynamically prunes edges to uncooperative agents, maintains convex, feedforward mentoring among cooperative agents, and computes global desired set points through a sparse linear relation consistent with leader references. The target set is abstracted by $N$ points that become final desired positions, enabling coverage-optimal transport while keeping computation low and guarantees intact. Extensive simulations demonstrate that, under full cooperation, all agents converge rapidly to the target zone with a 10\% boundary margin and under partial cooperation with uncooperative agents, the system maintains high convergence among cooperative agents with performance degradation localized near the disruptions, evidencing graceful resilience and scalability. These results confirm that forward-weight scheduling, hierarchical mentor--mentee coordination, and on-the-fly DNN restructuring yield robust, provably stable UAS transport in realistic fault scenarios.
