摘要
介绍了xPC实时目标环境,借助xPC平台实现了对某型大柔性多体结构卫星系统的半实物仿真试验开发。试验过程中,对xPC目标进行了二次开发,在星载计算机硬件不成熟时,采用一台xPC目标机来实现其快速控制原型,另一台目标机模拟星载计算机外部实时环境,由一台xPC宿主机分别控制两台目标机保证仿真时钟同步。在快速控制原型的基础上逐步地引入实物部件从而实现半实物仿真系统的构建。整个卫星地面半实物仿真系统的开发过程是一种基于模型的系统设计思想,实验结果证明了方法的有效性。
xPC real-time simulation system was introduced. By right ofxPC, Hardware-in-the-Loop Simulation （HILS） system of certain large flexible multi-body structure satellite was designed, During the experiment, xPC was further studied： an xPC host computer controlled two xPC target computers＇ at one time, One xPC target computer was used for imitating on-board computer, and the other one used for imitating outside environment of on-board computer. The final hardware was introduced to HILS system step by step after that the corresponding rapid control prototype worked successfully. The whole system development is based on model-based system design theory. Experiment results validate the presented method,
