卫星对空间目标悬停的轨道动力学与控制方法研究

Orbit Dynamics and Control of Satellites Hovering over Space Target

首先,给出了卫星悬停的轨道动力学模型,然后提出了悬停轨道的一种"持续式"的开路轨道控制策略,即通过在一段时间对轨道实施连续有限推力控制,使得在这段时间内卫星运行在新的悬停轨道上,而非开普勒轨道。最后,以地球静止轨道卫星为目标星,研究了悬停轨道的实施途径,并进行了数学仿真。仿真结果表明,在一段时间内对空间目标实施轨道悬停是可行的。

A successive open loop orbit control strategy suitable to hovering orbit was presented. By implementing a continuous pulse thrust control, the satellite was kept in a period of time on a new hovering orbit other than Kaplan orbit. Finally, taking earth synchronous satellites as a target, the implementation method of hovering orbit was studied, and numerical simulation was also conducted. The simulation results show that it is feasible to hover over special space targets in a period of time.
