摘要: 为实现空间两飞行器的交会对接,需要对空间交会对接过程进行仿真调试。为此,构建空间对接半实物仿真试验台,克服无实物仿真环境的局限性,再现2个空间飞行器的交会对接过程。提出对接机构测控系统设计方案,描述其软件结构和控制流程,建立对接机构测控模型,通过RT-LAB实时仿真平台将模型下载到测控计算机上运行,实现对接机构传感器信号的采集和运动控制。试验结果表明,该系统模型能够模拟飞行器的交会对接过程,具有较好的实时性,系统运行稳定、可靠。

Abstract: In order to implement the rendezvous and docking of two space aircrafts,the simulation debugging of the rendezvous and docking process must be done.So this paper builds a space docking hardware-in-the-loop simulation test-bed which overcomes the limit of no physical simulation environment.It can reproduce the rendezvous and docking process of two space aircrafts.The design scheme of measurement and control system for docking mechanism is put forward.Its software structure and control flow process are described,and the measurement and control model of docking mechanism is built.The model is downloaded to run through the RT-LAB real time simulation platform,and implements sensor signal sampling and motion control of docking mechanism.Experimental results show that the system model can simulate rendezvous and docking process of aircrafts.It has good real-time performance,and the system runs stably and reliably.

Key words: space rendezvous and docking, simulation measurement and control system, control flow, docking mechanism, simulation test-bed
