The invention relates to a spacecraft main-accompanying cooperative avoidance control method under accompanying satellite protection, which is applied to a one-chasing, one-escape and one-protection scene in which a task spacecraft performs avoidance under accompanying satellite cooperative protection near an orbit when unclear intentions of non-cooperative targets such as space debris and fault spacecrafts approach. The method comprises the following steps: firstly, establishing a dynamic model comprising a non-cooperative target, a guard accompanying star and a task spacecraft relative motion state; constructing a cost function of the two parties of the countermeasure by using the idea of the differential countermeasure; and then, a Hamilton-Jacobian method is adopted to solve the Riccati equation, and a full-state linear feedback control solution of the task spacecraft and the accompanying satellite is obtained. According to the method, the non-cooperative target can be prevented from approaching the important on-orbit task spacecraft as much as possible, the task spacecraft is assisted to avoid direct collision potential threats from the target through active shielding of the accompanying star, and the method accords with engineering practice.

    本发明涉及一种伴星护卫下的航天器主伴协同规避控制方法,应用于面对空间碎片、故障航天器等非合作目标的不明意图靠近时,任务航天器在轨道附近的伴星协同护卫下进行规避的一追一逃一护卫场景。首先建立包含非合作目标、护卫伴星以及任务航天器相对运动状态的动力学模型;再利用微分对策的思想构造对策双方的代价函数;之后,采用哈密尔顿雅各比方法,求解黎卡提方程,得到任务航天器和伴星的全状态线性反馈控制解。本发明可以尽可能地避免非合作目标靠近重要在轨任务航天器,通过伴星的主动遮挡来协助任务航天器规避来自目标的直接碰撞潜在威胁,契合工程实际。
