HLA架构下数值仿真与视景仿真集成方法的研究

以国产CZ系列运载火箭为研究对象,开发了基于HLA体系架构的全数字飞行仿真系统.通过建立运载火箭控制系统的数值仿真模型,围绕"模型实时驱动"这一核心功能设计了运载火箭全数字飞行仿真系统的框架结构并对其实现方法进行了描述,开发了Matlab-RTI中间件和OGRE- RTI适配器,较好地解决了数值仿真与视景仿真在HLA体系中的集成并保证了系统的实时性.应用集成方法完成的火箭飞行仿真系统已应用于西昌卫星发射中心的测发训练中,取得了较好的应用效果.

Research on Integration Method of Scene Simulation and Numerical Simulation Based on HLA

Adapting the CZ series Launch Vehicle as research object,the launch vehicle flying simulation system was developed.By establishing mathematical simulation model of Launch Vehicle control system,the architecture of Launch Vehicle flying simulation system was generated according to the requirement of real-time model driving.Using the method of developing Matlab-RTI middle piece and ORGE-RTI adapter,the integration of scene simulation and numerical simulation based on HLA was realized and the real-time performance of this system is sound.At present,the Launch Vehicle real-time flight simulation system based on this approach is being successfully applied in Xichang Satellite Launch Center.
