摘要: 针对轨道平面内某一方向发动机失效的情况,利用控制力的耦合效应,设计了航天器轨道转移的控制律。利用碰撞概率分析航天器发生碰撞的可能性,并结合燃料消耗选择一条碰撞概率小于给定的警戒值且燃料最优的转移轨道。最后通过仿真验证了发动机失效情况下的主动防撞机动控制律的有效性。

Abstract: A new control law of collision avoidance maneuver(CAM) is designed using coupling effect under a thruster failure. The collision probability is used to analyze the collision probability of two spacecrafts. And a transfer trajectory of orbit maneuver with safe and optimal fuel consumption is able to be selected in combination with the analysis of collision probability and fuel consumption. Simulation results validate that the CAM control law is effective under a thruster failure.

Key words: rendezvous and docking, CAM, collision probability, thruster failure
