发动机故障是运载火箭系统级单点故障,为提高系统的可靠性,以新一代大推力运载火箭为背景,针对飞行过程中发动机组中部分模块存在可测故障时,分析了控制力重构的原理,然后进行了控制力重构冗余算法的研究,并进行了算法的仿真验证。结果表明,该算法可以实现运载火箭控制力冗余作用。 In order to improve the reliability of the system, a new generation of high-thrust launch vehicle is taken as the background. When some of the modules in the engine assembly during flight have measurable faults, the analysis of the control force reconfiguration Principle, and then carried out the control force reconstruction redundant algorithm research, and the algorithm simulation. The results show that the algorithm can realize the controllability of the launch vehicle.
