摘要
为了实现直升机模拟训练器的仿真环境,提出一种基于嵌入式实时操作系统VxWorks和MATLAB/Simulink/RTW的半物理仿真技术,用来实现在连续紊流风场扰动下的实时在线仿真;在建立风场扰动下直升机非线性数学模型和连续紊流(Dryden)模型的基础上,实现了该仿真模型在RTW中的关键配置和在VxWorks环境中的程序解算;与数字仿真相比,该系统在实时性、在线性和真实性都得到了加强;仿真结果表明该方法的正确性及可行性,目前已被应用于某型直升机模拟训练器中。
To realize the simulation training device environment of the helicopter,embedded real time operating system VxWorks and the MATLAB / Simulink / RTW combination of semi-physical simulation method was proposed.Non-linear model of HEL with wind turbulence and continuous Dryden turbulence models were established,on this basis the simulation model key mapping techniques in RTW and program process in VxWorks were presented.Compared with the digital simulation this method has enhanced characters of the real-time,online and truthfulness.The simulation results verify the validity.
