摘要
介绍了小卫星控制系统地面半物理仿真验证平台的系统软硬件设计,并进行了姿态控制系统仿真验证。PC104实时仿真机作为平台核心,在气浮台上与星载计算机、敏感器、执行机构等实物组成闭环控制回路。引入数据库系统对仿真数据统一管理,联合地面显示终端实现了仿真数据的可视化及仿真过程的回放。利用建立的实时仿真系统,进行了卫星三轴姿态控制半物理仿真,结果表明本仿真验证平台系统软硬件结构的正确性。
The software-hardware design of the hardware-in-loop simulation platform for a small satellite control system was introduced and the simulation for the attitude control system was performed. As the keystone of the simulation platform, the PC 104 real-time simulator together with the on-board computer, sensors and actuators constitute a closed-loop control simulation system on an air-bearing table. A database was designed for the unified management of the simulation data ,and it combines with the ground display terminals to achieve the simulation data visualization and the playback of simulation process. Based on the established real-time simulation system, the hardware-in-loop simulation for satellite three-axis attitude control was done. The result of the simulation shows that the software-hardware architecture of this simulation platform is correct.
