基于反射内存网的分布式实时飞控仿真系统设计

摘要

A distributed real-time flight control simulation system based on VMIC network is developed. xPC and VMIC are used to build a real-time environment and network respectively. The traditional host -target machine model is broken through. The distribute layout is introduced to realize the simulation environment with a host corresponding to multiple target machine. The operating and visual display subsystems are designed to evaluate the control effects. The experiment results show that the characteristics of proposed system are the stable communication, the high-speed and high-reliability data transmission, the good effect visualization, the strong real -time capability and the high expansibility and openness.%提出了一种基于反射内存网的分布式实时飞行控制仿真系统；该系统采用xPC建立实时环境,通过反射内存卡组成实时网络,突破了传统xPC环境下一对一的主机—目标机模式；引入了分布式布局的思想,实现了—台主机对应多台目标机的仿真环境;通过构建外部模拟操作杆子系统和可视化显示子系统,实现了控制律响应效果的直观评价；实验结果表明,该系统通讯稳定,数据传输率和准确率较高,可视化效果好,实时性强,具有较强的开放性和可扩展性.
