Research on Key Technique of Rendezvous and Docking Training Simulation for Astronaut

交会对接飞行任务中,需要建立手控专项训练器对航天员进行训练。针对任务背景需要,研究建立了对接训练仿真中关键的轨道动力学模型、控制机构模型、测量机构模型以及GNC模型;进行了模型误差、解算误差和响应延迟等引起的天地一致性仿真偏差分析探讨,提出了解决方法。应用文中模型和误差解决方法建立的训练系统,分别进行了自主和人控模式下试验,结果表明满足训练设计指标要求,可作为工程实现重要参考。

In rendezvous and docking mission,the special manned docking training is needed by astronaut.To meet the demand of mission background,orbital dynamics model,control mechanism model,measurement mechanism model and GNC control model were established in the docking training simulator.To keep consistency of real space flight and training simulation,the error caused by modeling,resolving and response delay was investigated,and solutions were proposed.Using the established models and error solution,the training system was established,experiments were made in self-control mode and manned mode respectively.The results show that the training system meets the requirements of training design,and can supply references to engineering development of simulator.
