近空间飞行器具有飞行速度快、飞行包线大、气动特性变化剧烈及飞行环境复杂多变等特点,故障诊断与容错控制技术对提高其安全性和可靠性具有重要意义。本文通过对近空间飞行器故障诊断与容错控制技术的国内外研究现状调研和分析,阐述了近空间飞行器动力学模型及飞控系统的故障类型,分析了近年来国内外关于近空间飞行器故障诊断与容错控制技术的主要研究成果和存在的问题,最后对近空间飞行器故障诊断与容错控制技术未来的发展方向和面临挑战进行了展望。
Near-space vehicles are characterized by high flight speed, large flight envelope, dramatic changes in aerodynamic characteristics and complicated and varied flight environments. Fault diagnosis and fault-tolerant control technologies are of great importance to improve their safety and reliability. In this paper, the near-space vehicle fault diagnosis and fault-tolerant control technology research and analysis of the status quo at home and abroad, elaborated the near-space vehicle dynamics model and the flight control system of the fault types, analysis of recent years at home and abroad on near-space vehicle fault diagnosis and The main research results and existing problems of fault-tolerant control technology are discussed. Finally, the future development and challenges of fault diagnosis and fault-tolerant control technology for near space vehicles are discussed.
