To fully leverage the significant advantages of morphing glide vehicles (MGVs) over traditional fixed-configuration aircraft in terms of range
speed
and environmental adaptability
and to address the challenge of optimal morphing configuration decision-making under multiphysics coupling
an intelligent morphing decision-making method based on deep reinforcement learning is proposed. First
a deep neural network was used to construct a surrogate model for wing surface morphing and aerodynamic performance
achieving end-to-end rapid mapping from morphing actions to aerodynamic data. Then
a reinforcement learning framework was established by integrating the longitudinal motion model of the vehicle. Through comparative analysis of algorithm performance
the proximal policy optimization (PPO) algorithm was selected to construct the intelligent decision-making model
enabling autonomous policy learning under aerodynamic/morphing/traj ectory cross-coupling. Finally
full-process simulation experiments were conducted in perturbed environments beyond the training scope for validation. The results show that the proposed method can intelligently make morphing decisions by comprehensively considering the coupling effects of aerodynamics
morphing
and traj ectory
increasing the terminal range of the MGV by 7.304% and effectively maintaining a high lift-to-drag ratio flight state. Additionally
perturbation tests demonstrate that the method remains feasible and exhibits strong generalization capabilities in uncertain environments.
