基于正交试验设计的交会远距离导引误差分析

由于测量-规划-执行闭环过程的引入,交会远距离导引段的导航执行误差之间存在交互作用。对一个实际的远距离导引任务,采用正交试验设计方法安排数值试验,通过离差平方和评估误差之间的交互作用。结果表明,影响推进剂消耗的主要误差源之间存在显著的交互作用,而影响终端相对位置速度的主要误差源之间的交互作用很小或不明显。

Error Analysis for Rendezvous Phasing Based on Orthogonal Experimental Design

The navigating and executing errors which affect rendezvous phasing trajectory are coupled with each other when navigate - target - burn loop is employed. For an operational rendezvous phasing mission, the orthogonal design is used to organize the numerical experiments and the interaction between different errors is evaluated by the sum of devia- tion square. The results show that the major errors affecting propellant consumption have obvious interaction, while the in- teraction is small or not notable for the major errors whieh affect the terminal relative position and velocity.
