摘要
针对一般飞行控制半物理仿真系统中物理实物的确定性和不可替换性,提出了一种分布式结构半物理仿真系统方案。这种结构利用多台计算机分担模型解算任务,不但提高了数据处理的速度,而且使得各分系统的替换方便可行,仿真系统的半物理程度可灵活调节。系统还引入了以太网通讯,多线程机制和高精度定时技术来提高仿真系统实时性,最终实现了一个通用型的可远程启动和监控的飞行控制半物理仿真系统实验平台,取得了良好的仿真效果。
This paper developed a distributed architecture for HIL（ Hardware- In- Loop） simulation system, in which the hardware may be replaced by computers. The distributed architecture can improve Data Processing by using multiple computers share the task of solving model, and make the replacement of the subsystems facilitate. Ethernet, Multithreading and High- precision timing technology are implemented in the program to solve the system real- time requirement. The simulation platform accomplished with the function of remote start, and monitoring and manipulating.
