This paper proposes an innovative data-driven approach that combines deep reinforcement learning and process mining with Department of Defense Architecture Framework (DoDAF) views to learn and extract dynamic multi-UAV collaborative behaviors. First, a hierarchical multi-agent reinforcement learning framework is developed to simulate high-value complex maritime UAV collaboration, where agents learn implicit high-level task selection patterns while executing predefined low-level behaviors. Then, a DoDAF-oriented process mining algorithm is designed, which is the key innovation, to automatically extract DoDAF operational view-5b diagrams from learned behavioral pattern data. The experimental validation demonstrates this method excels at systematically extracting dynamic multi-UAV collaborative behaviors. The proposed approach could effectively bridge the gap between AI-based implicit behavior pattern learning and system engineering-based explicit behavior modeling requirement, contributing to the development of interpretable autonomous system and discovering effective collaborative behavior tactics.</p></div>","PeriodicalId":36309,"journal":{"name":"Aerospace Systems","volume":"8 2","pages":"447 - 466"},"PeriodicalIF":0.0,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145165340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to investigate the longitudinal dynamic characteristics of the missile, the nonlinear dynamic model is de-coupled to obtain its longitudinal motion equation. The aerodynamic parameters of the missile in the whole flight state envelope are simulated by quasi-steady assumption, and the aerodynamic coefficients under different flight environments and flared opening angles are obtained. The aerodynamic coefficients obtained from the simulation at each operating point are fitted to the flight altitude, Mach number, and the morphing rate of the flared skirt by the least square method. Finally, the parametric model of the aerodynamic coefficients is obtained. Finally, the aerodynamic coefficient function model is introduced into the longitudinal motion equation of the missile, and the longitudinal dynamic characteristics of the missile in different flight conditions are obtained by numerical simulation.

However, the use of a limited number of far-field measurement points in the reconstruction process exacerbates the ill-posedness issues, which necessitates the adoption of regularization techniques. The hierarchical Bayesian-based regularisation method has recently been applied to solve the equivalent source intensity distribution and reconstruct the sound field. However, previous methods have failed to accurately obtain the acoustic modal coefficients of the sound source, which are essential for determining the radiation type and directivity. This paper proposes a sound field reconstruction method that applies the hierarchical Bayesian algorithm to the source modal coefficient solution. Firstly, the deconvolution beamforming method obtains the sound source position. Subsequently, the hierarchical Bayesian algorithm is employed to obtain the source modal coefficients of the sound field, thereby completing the reconstruction of the sound field in the far-field region. Experimental results indicate that the proposed algorithm is highly effective in reconstructing far-field sound fields. Under free-field conditions and in mid-high frequency ranges, the average reconstruction error can be significantly reduced by using a few far-field microphones compared to traditional methods.</p></div>","PeriodicalId":36309,"journal":{"name":"Aerospace Systems","volume":"8 2","pages":"257 - 274"},"PeriodicalIF":0.0,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145142589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents an intelligent energy management system (EMS), which effectively regulates power flow between the PMFC and Li-Ion battery through a multi-input multi-output (MIMO) control framework.

FBM is a bio-inspired concept that incorporates flexible structural elements to facilitate morphing of the aerofoil shape in response to varying flight conditions. The NACA 2412 aerofoil is chosen for its camber adaptability, and CFD simulations are employed to assess the efficacy of FBM integration. The k–ω SST turbulence model is adopted for its ability to combine the strengths of the k–ω and k–ε models. The investigation encompasses a systematic exploration of geometric configurations, including trailing edge deflection at various chord lengths (0.6c, 0.65c, 0.70c, 0.75c, and 0.80c) and deflection angles (4°, 8°, and 12°). The results reveal that FBM aerofoils exhibit a consistent increase in maximum lift coefficient compared to conventional aerofoils across all deflection points and angles. Additionally, improvements in lift-to-drag ratio are observed. Furthermore, the stalling angle remains unaffected by deflection point variations, while deflection angle increments lead to corresponding increases in maximum lift coefficient. The morphing aerofoil with a 0.60c deflection point demonstrates the most significant enhancement in maximum lift coefficient, achieving a 13% increase at a 12° deflection angle.
