摘　　要：运载器发动机推力下降故障模式较为常见,对于典型的非致命故障采取姿态重构控制技术往往可以挽救一发飞行任务。随着计算机软件与硬件技术水平的提升,控制重构技术具有重大的意义。在此,开展了运载器故障动力学建模研究,提出了运载器重构控制技术方案。介绍了一种姿态重构控制技术研究成果,包括控制律设计与控制重分配方法,并针对所提出的姿态重构方法开展了仿真验证,结果表明姿态重构技术在发动机推力故障下仍可保证运载器良好的姿控性能与稳定能力。最后展望了智能控制技术发展前景。The engine thrust decreasing is a common failure of launch vehicle.For the typical non-fatal fault,the intelligent reconfiguration control technology can often save the flight mission.With the improvement of computer software and hardware technology,control reconfiguration technology is of great significance.The fault dynamic modeling of launch vehicle is carried out,and an intelligent control scheme is proposed.The research of attitude reconfiguration control is presented,including control law design and control allocation.And the simulation verification for the proposed intelligent attitude controller is studied.The results show that attitude reconfiguration technology can guarantee the flight performance and stability under an engine thrust failure.Finally,the development prospect of intelligent control reconfiguration is summarized.
