为了充分发挥变形滑翔飞行器(MGV)相较于传统固定构型飞行器在航程、速度及环境适应性方面的显著优势,解决多物理场耦合下的最优变形构型决策难题,本文提出了一种基于深度强化学习的智能变形决策方法。首先,利用深度神经网络构建翼面变形与气动性能的代理模型,实现了从变形动作到气动数据的端到端快速映射;然后,结合飞行器纵向运动模型建立强化学习框架,并通过算法性能对比,选用近端策略优化(PPO)算法构建智能决策模型,实现了气动/变形/弹道交叉耦合下的自主策略学习;最后,在训练范围外的拉偏环境中进行全流程仿真实验验证。结果表明:该方法能够综合气动/变形/弹道耦合影响进行智能变形决策,使MGV终端射程增加了7.304%,并能有效维持较高的升阻比飞行状态;同时,拉偏测试证明了该方法在不确定环境下依然具备良好的可行性与泛化能力。
To fully exploit the significant advantages of Morphing Gliding Vehicles (MGVs) over traditional fixed-configuration vehicles in terms of range
speed
and environmental adaptability
and to address the challenge of optimal configuration decision-making under multi-physics coupling
this paper proposes an intelligent morphing decision-making method based on deep reinforcement learning. Firstly
a deep neural network is employed to construct a surrogate model for wing deformation and aerodynamic performance
facilitating a rapid end-to-end mapping from morphing actions to aerodynamic data. Secondly
a decision-making framework is established by combining the longitudinal motion model with reinforcement learning. Through comparative analysis of algorithm performance
the Proximal Policy Optimization (PPO) algorithm is selected to construct the intelligent model
enabling autonomous strategy learning under the cross-coupling of aerodynamics
morphing
and trajectory. Finally
full-process simulation experiments are conducted in deviated environments outside the training envelope. The results indicate that the proposed method achieves intelligent decision-making by comprehensively considering the cross-coupling of aerodynamics
morphing
and trajectory
increasing the terminal range of the MGV by 7.304%
while effectively maintaining a high lift-to-drag ratio. Furthermore
deviation tests confirm the method's feasibility and generalization capability in adapting to uncertain environmental challenges.
