AI总结:

本文提出基于因果好奇心的因果机器学习方法,仅利用无人机轨迹即可识别恒定风、切变风和湍流,为恶劣天气下的最优轨迹设计提供轻量化方案。

摘要:

在本工作中,我们展示了无需专用传感器、仅利用无人机(UAV)轨迹并采用因果机器学习方法来估计无人机风环境的可能性。我们实现了因果好奇心方法,该方法将机器学习时间序列分类和聚类与因果框架相结合。我们分析了三种不同的风环境:恒定风、切变风和湍流,并探索了用于估计风况的最优无人机机动的不同优化策略。所提出的方法可用于在具有挑战性的天气条件下设计最优轨迹,并避免使用会增加无人机重量并损害其功能的专用传感器。

英文摘要:

In this work we demonstrate the possibility of estimating the wind environment of a UAV without specialised sensors, using only the UAV's trajectory, applying a causal machine learning approach. We implement the causal curiosity method which combines machine learning times series classification and clustering with a causal framework. We analyse three distinct wind environments: constant wind, shear wind, and turbulence, and explore different optimisation strategies for optimal UAV manoeuvres to estimate the wind conditions. The proposed approach can be used to design optimal trajectories in challenging weather conditions, and to avoid specialised sensors that add to the UAV's weight and compromise its functionality.
