基于螺旋伴飞式航天器交会控制技术

首次提出以螺旋伴飞式实现航天器交会的思路.在两航天器符合绕飞条件的前提下,从相对运动的Hill方程出发,首先推导出实现螺旋伴飞式交会的相对位置反馈控制律,这种相对位置反馈控制表明,航天器在交会过程中可以在只有相对位置测量条件下进行工作,因而具有一定的工程指导意义;进而,对螺旋伴飞式交会控制律的特点进行了分析,同时给出了稳定性分析与能量估算,分析表明这种交会控制技术,其控制具有较好的稳定性,且消耗能量较小;最后,通过一个空间圆绕飞轨道的伴星回收实例,给出了控制加速度的特性图和螺线回收轨迹图.仿真结果证明,伴星螺线回收轨道是可行的,并且具有优良的特性. 

A Control Technique for Rendezvous and Docking Based on Helix-approach Orbit of Inspector Satellite

For the control pattern of rendezvous and docking of spacecrafts, the impulse control method has been applied in common, but it deplete more energy. In this paper, the concept of helix-approach was firstly applied to the rendezvous and docking control of spacecrafts and the idea that by helix relative orbit the approach spacecrafts could rendezvous the aim spacecraft was proposed. First, the feedback form of law of control, which helps to realize helix-approach orbit, was educed with the Hill equtions. Then, the helix-approach orbit of Inspetor satellite in space circular fly-around relative orbit was fully studied,and the trait of helix-approach control was analysed, and stability of helix-approach control was explained, and fuel of wasting was estimated. Last, as a resut of simulations of return of Inspetor satellite in space circular relative orbit, figures of contorl acceleration and helix-approach orbit are shown, which the result of simulations indicates right stability, and it prove that the helix-approach relative orbit is not only feasible but also of fine characters.
