摘要
介绍了主动控制式对接机构对接的基本操作过程 ,并以具有六个作动阻尼器的主动控制式对接机构为例 ,对对接预捕获阶段作了详细的研究。建立了该阶段两对接飞行器的运动方程 ,给出了作动 /阻尼器为满足捕获条件所需达到的长度的计算方法 ,设计了控制回路 ,在此基础上作了数值仿真。仿真结果表明 ,建立的数学模型是正确的 ,设计的控制系统控制效果良好。
The basic operating process of the active control docking mechanism is introduced. The initial capture period of the active control docking mechanism with six actuators/attenuators is studied in detail. The dynamic model of two docking spacecrafts in this period is established. The length calculation method of the actuators/attenuators satisfied to capturing condition is presented. The numeric simulation result of the system model with feedback control shows the validity of system model and the effectiveness of servo control system.
