Embodied Anti-Interference Navigation Middleware for UAVs Based on Residual Reinforcement Learning
具身智能导航是无人机在低空复杂场景下实现自主作业的关键技术,但现有研究通常假设通信链路高度可靠,忽略了低空电磁频谱环境的动态干扰影响.为此,需将无人机具身导航从物理几何空间拓展至电磁频谱空间,实现物理障碍与电磁干扰的协同规避.然而,物理与电磁域的强耦合建模会导致状态空间指数膨胀,难以满足实时性与泛化要求.针对上述挑战,本文首次将中间件思想引入电磁频谱具身智能领域,提出无人机具身抗干扰导航中间件架构,作为嵌入任务规划层与飞控执行层之间的可插拔服务模块.该中间件通过构建残差马尔可夫决策过程(Residual Markov Decision Process,RMDP)将联合优化问题解耦为基准航向与抗干扰残差航向的叠加选择,使抗干扰校正策略仅需学习局部连续修正量,显著降低决策复杂度,在保证全局任务收敛的同时聚焦局部电磁风险抑制.在此基础上,设计残差强化学习算法,引入预测性状态编码机制将稀疏观测推演为广域干扰态势,从而实现前瞻性干扰规避,并结合离线预训练与受控在线微调的协同训练范式,有效解决未知电磁环境下的快速自适应与跨场景泛化难题.基于真实城市地图与真实机载设备的高保真仿真结果表明,所提方法单步决策仅需49.7 ms,多干扰源场景下任务成功率达到93.6%,体现出具身主动抗干扰能力.此外,挂载测试进一步验证该架构向上兼容多种异构全局规划器、向下满足物理几何域与电磁频谱域双重约束,具有可复用优势.
Embodied intelligent navigation enables UAV autonomy in complex low-altitude scenarios,yet existing re-search often overlooks dynamic electromagnetic interference.To mitigate this,it is essential to extend navigation from the physical geometric space to the electromagnetic spectrum,achieving synergistic avoidance of obstacles and interference.To address the state-space explosion caused by coupling these domains,this paper introduces the middleware paradigm into electromagnetic embodied intelligence and proposes a UAV Embodied Anti-interference Navigation Middleware.Embed-ded between the mission planning layer and the flight control execution layer,it functions as a pluggable service module.It utilizes a RMDP(Residual Markov Decision Process)to decouple the optimization problem into a baseline heading and an anti-interference residual heading.By limiting the policy to learning local continuous corrections,this design significantly reduces decision complexity.Consequently,it ensures global convergence while effectively suppressing local electromag-netic risks.We further develop a RRL(Residual Reinforcement Learning)algorithm incorporating a predictive state encod-ing mechanism to infer wide-area interference situations from sparse observations,enabling proactive interference avoid-ance.Additionally,a collaborative training paradigm combining offline pre-training with controlled online fine-tuning is ad-opted to ensure rapid adaptation and cross-scenario generalization in unknown environments.High-fidelity simulations based on real urban maps and authentic onboard equipment specifications demonstrate that the method achieves a 93.6% task success rate with a 49.7 ms decision latency.Integration tests further verify that the architecture is upwardly compatible with heterogeneous global planners and downwardly compliant with constraints,offering significant reusability advantages.
