摘要
为提高运载火箭在飞行中非致命故障和大偏差条件下的自适应能力,对运载火箭非致命故障下弹道规划制导和自适应重构控制国内外技术现状进行了分析,提出了火箭自主飞行重构方案,重点研究了轨迹规划方法制导化的弹道规划制导、控制参数自适应切换策略和控制指令重分配方法,开展了自主飞行重构仿真分析,完成了工程应用研究。仿真结果表明:自主飞行重构方法在运载火箭上可行,能够提升火箭应对不确定性和非致命故障的适应性。
To improve the adaptive capability of launch vehicle under non-fatal failure and large deviation conditions in flight,the development status quo of trajectory planning guidance and adaptive reconfiguration control technologies urgently needed by launch vehicles were analyzed,and a scheme of rocket autonomous flight control reconfiguration was proposed.The guidance scheme of trajectory planning method,adaptive switching strategy of control parameters and control instruction redistribution method were studied,and simulation analysis of autonomous flight control reconstruction was carried out to complete the engineering application research.The simulation results showed that the autonomous flight control reconfiguration method was feasible on the launch vehicle and could improve the adaptability to deal with greater uncertainties and non-fatal faults.
