| 摘 要： | 许多空间任务均需进行轨道交会,据任务的不同,对轨道交会的要求也不同,某些情况下需要跟踪星在交会的过程中暂时停泊于某一点,某些情况下对交会过程的视线角与轨迹提出一定的要求.针对这种需求,设计了一种闭环反馈控制方法,可以使跟踪星在设定的某点进行停泊及停泊保持,也可以沿设定的某条轨迹逼近目标,以满足不同任务对交会过程的不同要求.经仿真表明,此方法能够很好的满足任务要求,并具有精度高、能耗低、跟踪速度快的特点.

| Abstract: | The spacecraft orbital rendezvous technology is required for many missions,and the requirements of orbital control vary with the different tasks.In some cases,the tracker will be asked to stop in specified position temporarily;in other cases,the line-of-sight angle and trajectory are limited in the process of orbital rendezvous.To meet the different needs of various tasks,a closed-loop feedback control law was designed.By using this method of orbital control,the tracker can stop and keep in fixed point and approach target along the predetermined trajectory.The simulation shows that the control method has the advantages of fast tracking speed,high-accuracy,and low power consumption. |
