交会对接V-bar负向单脉冲撤离的轨迹安全性研究

Study on Trajectories' Safety of the-V-bar Single Impulse Departure During Rendezvous and Docking

研究了空间交会对接过程中V-bas负向单脉冲撤离的轨迹安全性问题。针对长方形禁飞区定义了两类安全的撤离模型;通过两个定理给出了这两种类型轨迹安全的充要条件,并加以证明;最后针对一组导航和控制都存在误差的撤离问题,通过选择合适的自由漂移初始相对速度,设计了制导脉冲,遍历仿真结果验证了单脉冲撤离理论的合理性和求解方法的有效性。

The trajectories＇ safety of-V-bar single impulse departure during rendezvous and docking was studied in this paper. First, with the rectangle keep-out-zone, two types of safe free flying trajectories after impulse were defined. Then the sufficient and necessary conditions of these trajectories＇ safety were put forward and proved. At last, a departure problem with uncertainty was solved and simulated. The results show that the theory of single impulse departure is reasonable and the method to get the solution is available.
