摘　　要：基于RTX的飞行器实时仿真在Visual C/C++开发环境下进行建模仿真,缺乏方便高效的建模工具,使得建模仿真存在诸多不便;针对该问题提出一种基于Simulink/RTW的RTX系统实时代码生成技术,通过对实时代码生成工具箱(RTW)中系统目标文件、模板联编文件和运行时接口支持文件的修改,直接将Simulink建立的图形化模型转化为RTX环境下可执行的实时仿真程序,大大简化了模型代码编写过程,提高仿真建模的效率;以该方法对某靶弹建模仿真,经测试仿真结果正确、实时性达到仿真要求。Real time simulation for aircraft based on RTX subsystem used Visual C/C＋＋ developing environment to develop. This de- veloping environment was lack of high efficiency modeling tools and made RTX inconvenient to be used in real time simulation. A real time simulation code generation technique based on Simulink/RTW was proposed in this paper. By modifying the system target file, template makefile and runtime interface support files of real time workshop, this method directly converted graphical models modeled by Simulink to executable real time simulation file of RTX. This simplified the process of writing simulation code and improved the efficiency of modeling. Experimental results showed that the results of the simulation were correct and with good real time performance.
