摘　　要：在自主空间交会任务中,星载量测系统的测量精度会对末端控制效果产生较大的影响。文章从自主近程导引的多脉冲控制律出发,通过解析方法分析测量误差对多脉冲控制精度的影响,并在此基础上,提出一种逆向算法以解决当指定导引的末端控制精度要求时,如何确定相应的测量误差的允许范围才能满足所期望的控制效果。最后仿真表明,通过逆向算法获得的测量允许误差,可以理想地达到要求的末端控制精度。Aim.The introduction of the full paper reviews Refs.1 through 11 and points out that there is an urgent need to explore but,to our knowledge,no paper in the open literature that explores the effect of measurement error on control precision.Sections 1 and 2 explain the results of our exploration.Their core consists of： a detailed study of the relationship between measurement error and control precision was performed via the reverse arithmetic in the area of autonomous rendezvous.The reverse arithmetic is based on the well-known theory of C-W rendezvous multi-impulse;the research on the effect of measurement error on control precision was carried out analytically based on the multi-impulse theory.And the reverse arithmetic was put forward to solve the problem of how much measurement error is allowable.The simulation results,given in Figs.4,5 and 6,and their analysis show preliminarily that the maximum permissible measurement error estimated by the reverse arithmetic is effective for the required control error.
