基于VxWorks的地形跟随半物理仿真平台的研究

摘要

In order to test the key techniques of a terrain following system and simulate the real flight effect of an aerocraft , a semi-physical simulation system based on VxWorks is developed. At the same time, the hardware configuration 、 subsystems function and soft structure of the system are analysed deeply , then the comunication problems are resolved. Besides , a technique of real-time code production based on MATLAB/RTW is used in this system , which can shorten the soft development cycle. At present , this system has been used in the project successfully , the result shows this system fully satisfy the requirements of terrain following in real-time simulation.%为了实现对地形跟随系统中关键技术的实时仿真验证,设计了一套基于VxWorks实时操作系统的半物理仿真平台;同时,对该仿真平台的硬件配置、子系统功能和仿真软件结构进行了深入分析,并解决了系统间的通信问题;此外.该仿真系统采用基于MAT-LAB/RTW的实时代码生成技术,缩短了仿真验证软件的开发周期;目前,该系统已经成功应用于工程项目中,仿真结果证明该系统完全满足地形跟随系统实时仿真的需要.
