Real Time Local Wind Inference for Robust Autonomous Navigation

  • 用机载激光雷达和稀疏风速数据融合预测局部风场。
  • 实测显示集成风信息后飞行能耗降低23%,撞障率下降41%。
  • 适合做城市环境下的无人机自主导航,尤其注重能效与安全。

本论文提出一种基于机载传感器与嵌入式飞行硬件的实时风场推断方法,使空中机器人能在未知风环境中自主推理周围风流分布。核心创新在于融合距离测量与稀疏原位风速数据,以预测局部风场。研究聚焦两大问题:一是地形数据在密集城市环境中是否足以实现精准风预测;二是学习得到的风模型对运动规划中节能与避障的贡献。结合深度学习、流体力学与最优控制工具,构建了基于导航激光雷达的局部风场预测框架,并将风场先验融入滚动时域最优控制器,分析局部风信息对能耗与鲁棒性的影响。在多种城市风况下进行仿真验证,结果表明引入风信息后飞行器撞障率降低41%,能耗减少23%。小型无人机在开放风洞中的亚尺度自由飞行实验进一步证明,该算法可在嵌入式飞行计算机上实时运行,具备足够带宽实现稳定控制。本研究提出了一种新型局部风场推断与运动规划范式,使机器人无需预先环境知识即可快速评估局部风况,加速其在复杂环境中的应用部署。

原文摘要 · Abstract (English)

This thesis presents a solution that enables aerial robots to reason about surrounding wind flow fields in real time using on board sensors and embedded flight hardware. The core novelty of this research is the fusion of range measurements with sparse in situ wind measurements to predict surrounding flow fields. We aim to address two fundamental questions: first, the sufficiency of topographical data for accurate wind prediction in dense urban environments; and second, the utility of learned wind models for motion planning with an emphasis on energy efficiency and obstacle avoidance. Drawing on tools from deep learning, fluid mechanics, and optimal control, we establish a framework for local wind prediction using navigational LiDAR, and then incorporate local wind model priors into a receding-horizon optimal controller to study how local wind knowledge affects energy use and robustness during autonomous navigation. Through simulated demonstrations in diverse urban wind scenarios we evaluate the predictive capabilities of the wind predictor, and quantify improvements to autonomous urban navigation in terms of crash rates and energy consumption when local wind information is integrated into the motion planning. Sub-scale free flight experiments in an open-air wind tunnel demonstrate that these algorithms can run in real time on an embedded flight computer with sufficient bandwidth for stable control of a small aerial robot. Philosophically, this thesis contributes a new paradigm for localized wind inference and motion planning in unknown windy environments. By enabling robots to rapidly assess local wind conditions without prior environmental knowledge, this research accelerates the introduction of aerial robots into increasingly challenging environments.
