对高超声速飞行器研制过程中最为关键的技术之一——再入容错制导技术进行了综述。回顾了高超声速飞行器容错制导研究概况;针对高超声速飞行器产生执行器、传感器、结构等故障引起气动参数在内的系统各项参数发生变化,已有的再入制导轨迹已经不能满足制导要求的问题,进行再入容错制导方法研究,找到故障情况下最优再入轨迹;介绍了几种再入容错制导方法,并对未来技术的发展进行了展望。
One of the most important technologies in the development of hypersonic vehicle, reentrant fault-tolerant guidance technology, is reviewed. The research status of hypersonic vehicle fault-tolerant guidance is reviewed. For the hypersonic vehicle, various parameters of the system such as actuators, sensors and structures that cause aerodynamic parameters are changed. The existing reentry guidance trajectory can not meet the guidance requirements , Research on fault-tolerant guidance re-entry method and finding the optimal reentry trajectory under fault conditions; introduce several reentrant fault-tolerant guidance methods and prospect the development of future technologies.
