八项实验表明，安全考虑将在未来飞行任务的成功中发挥重要作用。本文提出了一种在线生成安全的，燃料优化的交会轨迹，保证避免碰撞的一大类异常系统行为的方法。我们研究的成本施加安全作为一个问题的约束和额外的约束，保证无限地平线被动碰撞避免，同时使未来的对接重试。被动和主动的安全方法之间的Tradeos检查。一个凸制定的避碰算法的介绍，并示出提供更快的解决方案，只有一个小的额外的燃料费用。使用旋转和非旋转目标的许多例子，展示了整体benets纳入这些安全约束相比，标称轨迹设计技术。
ight experiments suggest that safety considerations will play an important role in the success of future missions. This paper presents a method for online generation of safe, fuel-optimized rendezvous trajectories that guarantee collision avoidance for a large class of anomalous system behaviors. We examine the cost of imposing safety as a problem constraint and of additional constraints that guarantee innite horizon passive collision avoidance while enabling future docking retries. Tradeos between passive and active approaches to safety are examined. A convex formulation of the collision avoidance algorithm is introduced and shown to provide much faster solutions with only a small additional fuel expense. Numerous examples using both rotating and nonrotating targets are presented to demonstrate the overall benets of incorporating these safety constraints when compared to nominal trajectory design techniques.
