针对近距离交会对接特点,提出一种由制导脉冲确定的交会对接安全带概念,在标称轨迹附近分别设计无控带、修正带、警戒带和紧急撤离带和基于安全带的制导策略.仿真结果表明,该制导策略能及时敏感部分故障,且燃料消耗不大,是燃料消耗和轨迹安全折中的一种制导策略.
Aiming at the characteristics of short-range rendezvous and docking, a concept of rendezvous and docking seatbelt determined by guidance pulse is proposed, and the guidance strategies of no-control zone, correction zone, warning zone and emergency evacuation zone and seatbelt are designed respectively near the nominal trajectory. The results show that the guidance strategy can be sensitive to some failures in time, and the fuel consumption is not big, which is a guidance strategy for fuel consumption and trajectory safety.
