基于HLA的实时仿真方法的研究与测试

实时性是某些仿真系统的重要性能指标.分析了运行支撑环境(RTI)消息基本流程及高层体系结构(HLA)时间管理服务对仿真实时性的影响,提出采用多步推进+墙钟控制的时间推进方式来实现实时仿真,并设计了一种测试RTI实时性的试验方案,以及用该试验测试了MAKRTI2.3.3在两种传输服务下的实时性,仿真结果表明,在高速局域网下,采用多步推进的时间推进方式能有效提高仿真实时性,基本上达到大多数半实物仿真系统的实时要求.

Test to real time performance of real-time simulation method based on HLA

To improve the real time performance of the simulation, the impacts of key techniques such as architecture, communications, time management (TM) and data distribution management (DDM) algorithms to the real time performances of Run Time Infrastructure (RTI) are analyzed, and an approach to improve the performances of real time is presented. According to the data collected from the experiments, the performances of real time performance of Multi-step Advancing + Wall-Clock Regulating are compared and analyzed. The result shows that the system based on high level architecture (HLA) using the TM of Multi-step Advancing improve the real-time performance.
