Research on the Missile Hardware-in-Loop Simulation Programming Technology Based on Real-Time Extension of Simulink

为了编制实时、稳定运行的导弹半实物仿真程序,研究了基于Windows+RTX实时环境下编制导弹半实物仿真程序的技术。利用MATLAB/Simulink/RTW软件工具图形模块化设计导弹仿真模型,并转换成C语言程序;对C语言程序进行实时性改进和移植,形成能够在Windows+RTX实时环境下稳定运行的仿真程序;以某型导弹的半实物仿真为例,设计的仿真程序能在Windows+RTX实时环境下运行,验证了该方法的正确性、可行性。

In order to design a real-time and stable program for missile hardware-in-loop simulation,the technology of editing missile simulation program base on Windows Real-time Extension was researched.Using MATLAB/Simulink/Real-time Workshop,the missile simulation model was established in graphic model.Then,the simulation model was changed to be a C-language program.The C-language program was improved to be real-timely and transformed to be a stably simulation program running in Windows Real-time Extension.A hardware-in-loop simulation of a typical missile was used to be an example.The simulation program of the missile was designed to run in Windows Real-time Extension.It is verified that this method is correct and feasible.
