摘要
在分析目前设计指标合理性的基础上,提出一种交会对接地面导引与自主导引的切换条件约束模型,通过约束追踪航天器自主导引段初始相对运动轨迹在轨道面内的振荡幅度和含偏差自主控制过程中的推进剂消耗,给出保证自主寻的成功条件下,地面导引终点不同方向偏差间的取值关系。结合交会对接任务系统仿真,分析验证约束模型的正确性和合理性。
On the basis of analysis of the reasonableness of the design indexes, a switching condition for rendezvous and docking between phasing and homing is provided. Considering both the initial relative trajectory＇s vibration amplitude in the orbital plane and the propellant consumption in the process of autonomic control,the relationship between deviation values at the end of phasing in different directions is given. By simulating,the effectiveness and rationality of the switching conditions are verified.
