Research on Uncertainty Measurement Method of Aircraft HWIL System

不确定性是仿真系统的固有属性,导致仿真系统的预估结果在某种程度上与真实结果不一致,影响系统的稳健性和可靠性。本文在分析飞行器半实物仿真系统不确定性特点基础上,提出了半实物仿真系统不确定性度量分析框架,研究了适合半实物仿真系统的基于随机/认知/混合的分类、合成和系统不确定度量方法,并以典型仿真对象为例,开展了分类不确定性度量方法的应用研究,检验了分类不确定性度量方法的有效性,为后续不确定性度量结果对于系统的影响研究奠定基础。

Uncertainty is the inherent attribute of simulation system, causing the expected results inconformity with the real results, even influencing the robustness and reliability of system. Based on the analysis of the system uncertainty characteristics, the analysis framework of HWIL system uncertainty measurement is proposed. Three kinds of the uncertainty measurement methods based on the uncertainty type and the compound and weighting are researched on aircraft HWIL System. The typical uncertainty measurement methods are applied based on some aircraft HWIL system and the result proves that the method is efficient.
