摘要: 针对低空风场中强空间非均匀特征带来的重载无人机能效与安全协同路径规划的非凸优化难题,本文提出一种融合流场动力学特征的物理感知图神经网络引导 A*搜索的协同路径规划框架(PI-GNN-A*)。该框架首先基于流体力学机理构建融合涡度特征的稀疏物理图,赋予模型对流场各向异性的感知能力;其次,设计增强型非对称损失函数,通过惩罚低估误差将安全约束内化为启发式势场的保守偏置,有效平衡搜索效率与风险规避。基于二维稳态兰金涡旋场的理想化原型验证与统计检验表明:本文方法在计算效率、飞行安全和气动能效之间达成高鲁棒性的协同权衡,相比于缺乏显式物理约束的常规神经网络启发算法,本文方法在嵌入涡度特征后有效抑制了空间的盲目试探,搜索效率实现了统计学意义上的显著提升;相比Dijkstra算法,本方法以约8.0%的代价退化为合理让步,换取搜索空间50.8%的缩减;相比传统基于人工势场的风场感知方法,本文方法以适度的搜索开销为合理代价,在保证全局综合代价非劣的同时, 将系统的抗风安全裕度从5.08%拓宽至6.17%,相对提升21.46%,为算力受限的机载平台提供更快的路径重规划能力。

Abstract: To address the non-convex optimization challenge of synergizing energy efficiency and safety path planning for heavy-lift Unmanned Aerial Vehicle (UAV) in low-altitude wind fields with strong spatial non-uniformity, this paper proposes a collaborative path planning framework (PI-GNN-A*) using an A* search guided by a Physics-Informed Graph Neural Network integrating flow field dynamic features. First, based on fluid dynamics mechanisms, a sparse physical graph incorporating vorticity features is constructed to empower the model with the capability of perceiving flow field anisotropy. Then, an enhanced asymmetric loss function is designed. By penalizing underestimation errors, this function internalizes safety constraints into a conservative bias within the heuristic potential field, effectively balancing search efficiency with risk avoidance. Idealized prototype validation and statistical tests on two-dimensional steady-state Rankine vortex fields demonstrate that the proposed method achieves a highly robust synergistic trade-off among computational efficiency, flight safety, and aerodynamic energy efficiency. Compared to conventional neural network heuristic algorithms lacking explicit physical constraints, the proposed method, after embedding vorticity features, effectively suppresses blind spatial exploration and achieves a statistically significant improvement in search efficiency. Compared to the Dijkstra algorithm, the proposed method obtains a 50.8% reduction in search space as a reasonable trade-off for an approximate 8.0% degradation in comprehensive cost. Compared to traditional wind-field-aware methods based on artificial potential fields, the proposed method, at the reasonable expense of a moderate search overhead, broadens the wind-resistant safety margin of the system from 5.08% to 6.17% (a relative increase of 21.46%) while ensuring noninferior global comprehensive cost, providing faster path replanning capabilities for airborne platforms with limited computing power.
