基于xPC的实时飞行仿真系统结构设计

Design of a Real-time Aviation Simulation System Based on MATLAB/xPC

文章讨论了如何在MATLAB/xPC平台上开发一个开放式工程仿真系统。该系统与通常仿真系统的主要区别是,可根据新型飞机设计的不同需求,使用MATLAB/Simulink方便地建模,并对新产生的仿真信息进行开放式的管理。改变了以往仿真需求改变则需开发不同仿真系统的一次性开发模式。在这个开放式的工程实时飞行仿真系统中,主要讨论了开放式仿真系统的信息管理及以往仿真监控组件如何在MATLAB/xPC环境下的无缝集成问题。针对这些问题提出并设计了基于工作站级的结构模型及开放式目标监控接口模板;应用实践表明,该系统不仅继承了MATLAB建模方便快捷的特点,而且具有通常仿真系统的各种功能,是一个集飞机设计,新方案实验,飞行模拟及飞行试验数据分析于一身的无纸的新型飞机的设计平台。

This article discusses how to develop an open engineering simulation system based on MATLAB/xPC.The main difference between this system and traditional simulation systems is that it can easily build a model with MATLAB and openly manage its new simulation information based on new requirements of new aircrafts.It gets rid of the one-off development model in which people should develop different system for different simulation objectives.As for this open engineering real-time aviation simulation system,this article mainly discusses the information management and the seamless integration of simulation monitoring components into MATLAB/xPC environment.As the solution,a workstation level structure model and an open target monitoring interface template are given.Application practice showed that this system not only inherits the merits of easy and fast model-building of MATLAB but also possesses common functions of traditional simulation systems,which makes it a new aircrafts＇ paperless design platform for designing aircraft,making experiments for new plan and analysing aviation experiment data.
