摘要:

针对长航时可复用飞行器舵回路故障检测、诊断、预测中存在的可量测数据少和数据不全面的问题,将数字孪生引入至舵回路健康管理中。首先,提出了一种舵回路系统的数字孪生框架,通过AMESim和FLUENT对舵回路进行了机、电、控制和飞行动态负载的精细化建模,并实现了三相机电控制和飞行实时动态负载模型的耦合集成。然后,为解决舵回路数字孪生与物理实体在正常、舵面缺损和松浮故障等多种运行状态中保持虚实一致的问题,构建了舵回路虚实一致性感知方法及数字孪生动态调整机制,使得舵回路数字孪生通过在线故障感知与加载,具备持续跟踪实体变化并保持虚实一致性的能力。最后,实验表明,正常和故障下所建舵回路数字孪生虚实电流和舵角的多项时域指标的幅值与趋势均能与物理实体保持虚实一致,且经孪生扩展的数据维度可为舵回路健康管理提供更全面的数据支撑。

Abstract:

To address the challenges of limited and incomplete measurable data in fault detection, diagnosis, and prediction of the rudder-loop-system in long-endurance reusable aircraft, this study introduces a digital twin-based approach for health management of the system. First, a digital twin framework for the aircraft’s rudder-loop-system is proposed, incorporating high-fidelity modelling and simulation of mechanical, electrical, control, and dynamic flight load subsystems using AMESim and FLUENT. The integrated model realizes the coupling of three-phase electro-mechanical control with real-time flight dynamic loading. Subsequently, to ensure consistency between the digital twin and the physical system under various operational conditions including normal, rudder surface degradation, and loosening faults, a virtual-physical consistency perception method and a dynamic adjustment mechanism are developed. This enables the digital twin to continuously track physical system changes and maintain synchronization through online fault perception and dynamic updating. Finally, experimental results demonstrate that under both normal and faulty conditions, the digital and physical systems exhibit consistent trends and amplitudes in multiple time-domain indicators of rudder current and deflection angle. Moreover, the expanded data dimensions provided by the digital twin enhance the comprehensiveness of data available for health management. This research highlights the potential of digital twin applications in improving the reliability and maintainability of electric rudders in advanced flight systems.
