运载火箭自适应减载控制技术
|
摘要
为减小新型中型运载火箭飞经大风区的气动过载,保证箭体结构安全,采用主动减载控制设计,分析了基于扩张状态观测器的自适应减载控制方法,基于过载传感器的减载控制方法,以及将两种技术结合的使用方法。仿真分析结果表明,针对新型中型运载火箭,3种自适应减载控制方法对减小气动过载均具有一定的效果。基于加速度表的过载控制在标称状态下具有较好的减载效果。
In order to reduce the aerodynamic overload of new launch vehicles flying across the strong wind area and is ensure the structural safety, adaptive Load-relief control technology based on extended state observer(ESO) and overload sensor are both studied,thus a combining method based on informed research is introduced into the flight control system. The simulation results indicate that the methods are capable for reducing aerodynamic overload of new launch vehicles.
