Review on data-driven health state on-line estimation methods for aircraft electromechanical system components

飞机机电系统的机电部件(飞机机电系统部件)处于良好的健康状态是飞机机电系统安全运行重要前提,对于保障飞机正常飞行和成员安全具有重要意义。飞机机电系统部件健康状态在线估计可以实现部件健康状态的在线估计,有效支撑部件的视情维修,进而为飞行任务保障提供决策参考。本文以代表性飞机机电系统部件机电作动器和辅助动力装置为具体研究对象,在对该领域健康状态估计方法进行充分调研基础上,阐述飞机机电系统部件健康状态估计基本概念及内涵,并针对飞机机电系统部件数据驱动健康状态在线估计方法体系进行系统地分析,进而归纳总体发展动态并展望未来发展方向,以此为相关研究者提供参考。

The good healthy state for the components of aircraft electromechanical system(aircraft electromechanical system components) is an important prerequisite for the safe operation of the aircraft electromechanical system, which is of great significance to ensure the normal flight of the aircraft and the safety of the crew. The health state on-line estimation of electromechanical system components can realize the on-line estimation of component health state, and effectively support the condition-based maintenance of components and then provide decision-making reference for flight mission support. In this paper, the health state estimation methods in this field are fully analyzed, in which the typical representative of them, namely Electro-mechanical Actuator and Auxiliary Power Unit, are taken as the specific research objects. The basic concept and connotation of the estimation of the health state for aircraft electromechanical system components are presented, and the data-driven health state on-line estimation method for aircraft electromechanical system components is analyzed systematically. On this basis, the overall development trend is summarized, and the future development direction is prospected to provide references for the related researchers.
