基于RTW和VxWorks的飞行控制系统实时仿真

介绍了一种使用Simulink/RTW建模工具和Tornado/VxWorks嵌入式实时操作系统进行飞行控制系统快速原型的方法。首先对一个非线性的纵向短周期运动的飞机模型进行了线性化后的动态逆控制系统的设计。该控制系统满足C^＊准则。然后使用Simulink的模型代码自动生成技术,生成经优化的可直接在VxWorks系统上实时运行的应用程序,并且能够实时监控目标机的运行状态以及对Simulink模型实现在线调参。接着,以Pentium4处理器微机为目标机,在以太局域网的环境中下载可执行模块,实时运行和监控目标机的运行。最后,将实时仿真的结果与Simulink的数字仿真结果进行了对比分析。

Real-Time Simulation of Flight Control System Based on RTW and VxWorks

A rapid prototype method of flight control system was introduced based on RTW in Matlab/Simulink and Tornado/VxWorks. A nonlinear longitudinal short-period aircraft model was given. And a dynamic inversion control system satisfied with the C*.criterion was designed by feedback linearization. RTW generates optimized source code and executable modules by using auto generator from the Simulink models. When running in Vxworks, the modules can be monitored real-time and regulated online. In an ether local area net (LAN) environment, the modules were downloaded to the target computer based a Pentimum4 personal computer and run real-time. Compared with the results only in Simulink, the comparison simulation result figures and some conclusions were given.
