基于HLA的实时仿真研究

Research of Real-Time Simulation Using HLA

服务,联邦成员依靠墙上时间(简称WCT)进行DR推算和接收RO消息,但这往往会引起因果倒置和逻辑颠倒。本文阐述了当前HLA用于实时仿真的局限性和存在的问题,分析了实时仿真的运行模型,针对HLA的实时问题提出了解决方案,并对HLA中接口规范进行了实时扩展,构想了一个实时RTI的体系结构。

Most real-time simulations based HLA do not use time management services of RTI. Federates progress dead- reckoning and receive ordering messages relying on wall-clock time, which sometimes brings problems of causal and temporal anomalies. This paper shows limitations and problems of current real-time simulation using HLA, analyzes the running model of real-time simulation, brings forward solutions schemes for real-time problem of HLA, presents a proposal of a real-time extension of HLA, and assumes an architecture of real-time RTI.
