摘要: 空间站在轨组装和长期运营阶段涉及到多飞行器独立飞行、飞行器间交会对接、多飞行器组合体融合控制、多飞行器分离过程控制和飞行器返回再入等复杂飞行任务,完整、真实的飞行模拟是必需且至关重要的.基于时间同步、实时数据交换的分布式一体化仿真架构,设计了一种多飞行器协同的通用半物理制导、导航与控制(guidance,navigation and control,GNC)系统飞行模拟平台,可很好地满足复杂系统的飞行模拟需要.平台由若干灵活、可扩展的通用模拟器构成,单个模拟器通过配置可以实现任一飞行器的功能,能够独立对指定飞行器的全任务过程进行仿真.平台通过靶场仪器组B时间码(interrange instramentation group B,IRIG B)信号进行时间同步,利用1553B总线完成动力学仿真数据实时交换,并在多模拟器之间通过协调机制实现热并网后进行协同仿真.该模拟平台成功应用于空间站飞行控制演练.

Abstract: A method for designing simulation platform of the spacecraft Guidance Navigation & Control (GNC) system is proposed. During the in-space assembly and long term operation of the Chinese Space Station, complex flight missions are involved, including multi-spacecraft individual on-orbit flight, space rendezvous and docking, multi-spacecraft combination fusion control, separation process control and spacecraft re-entry. The integrate and realistic flight simulation is necessary and vital. Based on time synchronization, real-time data exchange, distributed and integrated simulation architecture,a universal multispacecraft collaborative Hardware-in-the-Loop (HIL) simulation platform of GNC system is proposed, on which integrate flight simulation with high fidelity is possible to be achieved. The platform consists of several universal simulators, which are highly flexible and expandable, and each can be configured as any specific spacecraft and perform the spacecraft’s whole mission process flight simulation independently. The platform synchronizes time via IRIG-B code and exchanges dynamics data on 1553B bus in real-time, and multi-spacecraft co-simulation can be implemented after coordination accomplished among simulators. This simulation platform has been successfully applied in a spacecraft flight control drilling program.

Key words: Chinese space station, multi spacecraft collaborative, hardware-in-the-loop (HIL), guidance navigation &, control (GNC), flight simulation
