  • 将多机路径规划转为分层概率推断问题,利用专家演示构建世界模型。
  • 在线运行时通过最小化异常指标实现任务分配、路径插入与避障重规划。
  • 适合需要实时自适应的无人机群系统,对噪声数据也有良好鲁棒性。

本文提出一种受专家引导的主动推理启发框架,用于自适应无人机群轨迹规划。该方法将多无人机轨迹设计从反复的组合优化问题转化为分层概率推断问题。离线阶段,基于排斥力避碰的遗传算法规划器(GA--RF)生成专家示范,并抽象为任务、路径和运动三类词典。这些词典用于学习一个概率世界模型,捕捉专家任务分配如何诱导路径顺序,以及路径顺序如何引发运动级行为。在线运行时,无人机群通过形成对符号状态的后验信念,并最小化相对于专家参考分布的KL散度异常指标,评估候选动作,从而实现任务分配、路径插入、运动适应及碰撞感知重规划,无需重新运行离线优化器。在运动层级集成贝叶斯状态估计算法(包括EKF和PF模块),提升不确定性下的轨迹修正能力。仿真结果表明,所提框架保持专家式规划结构的同时,生成轨迹比改进的Q-learning更平滑、更稳定。使用真实飞行无人机轨迹数据的额外验证表明,所学世界模型可在噪声和非光滑观测下纠正符号预测,支持其在自适应无人机群自主中的应用。

原文摘要 · Abstract (English)

This paper presents an expert-guided active-inference-inspired framework for adaptive UAV swarm trajectory planning. The proposed method converts multi-UAV trajectory design from a repeated combinatorial optimization problem into a hierarchical probabilistic inference problem. In the offline phase, a genetic-algorithm planner with repulsive-force collision avoidance (GA--RF) generates expert demonstrations, which are abstracted into Mission, Route, and Motion dictionaries. These dictionaries are used to learn a probabilistic world model that captures how expert mission allocations induce route orders and how route orders induce motion-level behaviors. During online operation, the UAV swarm evaluates candidate actions by forming posterior beliefs over symbolic states and minimizing KL-divergence-based abnormality indicators with respect to expert-derived reference distributions. This enables mission allocation, route insertion, motion adaptation, and collision-aware replanning without rerunning the offline optimizer. Bayesian state estimators, including EKF and PF modules, are integrated at the motion level to improve trajectory correction under uncertainty. Simulation results show that the proposed framework preserves expert-like planning structure while producing smoother and more stable behavior than modified Q-learning. Additional validation using real-flight UAV trajectory data demonstrates that the learned world model can correct symbolic predictions under noisy and non-smooth observations, supporting its applicability to adaptive UAV swarm autonomy.
