摘要: 在交会对接轨道控制任务的停靠阶段,系统需要进行平滑无超调、鲁棒性好、节约燃料的控制,为此,在轨道控制中引入过渡过程,设计了基于过渡过程的空间交会轨道控制器。在系统的初始坐标和目标坐标之间,将最终目标细化分级为逐步到达的平滑的S型曲线形式,设计了3种不同的基于过渡过程的空间交会轨道控制器。仿真实验表明所提出的过渡过程可以使系统以高精度平稳的方式完成轨道控制任务,使简单的控制器也可完成控制任务。

Abstract: In the docking phase of orbit control task of space rendezvous and docking, smooth without overshoot, good robustness and fuel-saving control are required. To this end, a transient process for orbit control was proposed, and new controllers were designed on the basis of the transient process for the space rendezvous and docking. The ultimate goal was refined to the gradual arrival goal to build the transient process between the initial coordinate and the target coordinate of the system. The output of the transient process was designed as a smooth S-type curve. Three different orbit controllers of space rendezvous and docking were analyzed. The simulation results indicate that the system task can be completed in a high accuracy and stable way by adding the transient process in the orbit control task, and the common controllers can be used to complete the task by adding the transient process.

Key words: orbit control, rendezvous and docking, transient process, golden section control
