  • 适合需要高可靠性的复杂飞行器研发团队使用。

近年来,动态系统多学科设计方法发展迅速,其中并行概念设计与控制设计(共设计)理念备受关注。该方法通过同步调整前馈/反馈控制策略与系统概念设计,旨在获得超越传统分离设计的集成解决方案。尤其在尾坐式无人机等混合型无人航空系统中,灵活性(受控制影响)与效率(受结构设计影响)常存在矛盾。然而,理论模型与真实环境之间的‘现实差距’仍是关键挑战,导致设计部署后性能不理想。为此,本文提出DAIMYO架构,将高保真环境仿真融入设计流程,追求‘一次成功’的设计目标。该方法生成的无人机设计方案兼具多功能性与高效性,能有效应对现实差距带来的挑战。

原文摘要 · Abstract (English)

In recent years, there has been a notable evolution in various multidisciplinary design methodologies for dynamic systems. Among these approaches, a noteworthy concept is that of concurrent conceptual and control design or co-design. This approach involves the tuning of feedforward and/or feedback control strategies in conjunction with the conceptual design of the dynamic system. The primary aim is to discover integrated solutions that surpass those attainable through a disjointed or decoupled approach. This concurrent design paradigm exhibits particular promise in the context of hybrid unmanned aerial systems (UASs), such as tail-sitters, where the objectives of versatility (driven by control considerations) and efficiency (influenced by conceptual design) often present conflicting demands. Nevertheless, a persistent challenge lies in the potential disparity between the theoretical models that underpin the design process and the real-world operational environment, the so-called reality gap. Such disparities can lead to suboptimal performance when the designed system is deployed in reality. To address this issue, this paper introduces DAIMYO, a novel design architecture that incorporates a high-fidelity environment, which emulates real-world conditions, into the procedure in pursuit of a `first-time-right' design. The outcome of this innovative approach is a design procedure that yields versatile and efficient UAS designs capable of withstanding the challenges posed by the reality gap.
