摘要
针对目前基于HLA的半实物仿真的实时性不强的特点,在分析该实时性问题的基础上,利用数据分发服务DDS,设计了一种基于DDS和HLA的实时性联合仿真系统。该系统通过使用DDS替换HLA中的数据分发功能,利用HLA进行仿真系统中的联邦管理,并使DDS负责仿真节点间的数据分发功能,在半实物仿真中达到了实时仿真的目的。试验结果表明:该联合仿真系统结构能显著提高基于HLA的半实物仿真系统的实时性,能有效满足分布式仿真的实时性需求。
First the real-time problem of the hardware-in-the-loop simulation with HLA is analyzed. Then a real-time simulation system based on DDS ＆ HLA is designed. The combined system makes use of DDS responsible for data distribution and HLA managing the simulation federation to achieve the real-time simulation. Finally an experiment shows that the combined system could improve the real-time ability of the simulation system with HLA.
