摘    要:故障诊断技术是提高故障检测和隔离能力,提高任务可靠性的重要手段,基于模型的故障诊断分析方法得到了广泛应用,但难以用于实时检测诊断,难以计算虚警率等设计指标。本文提出扩展多领域物理系统建模语言Modelica,将多种故障模态嵌入模型中,利用基于假设的真值维护系统(ATMS)方法分析了测试集的生成算法。理论上分析了计算虚警率的可行方案,体现了新模型的优势。

关 键 词:测试性  故障诊断  基于模型  基于假设的真值维护系统

Abstract:Failure Diagnosis is an important means to improve mission reliability,fault detection and isolation rate.Model -based fault diagnosis methods has been widely used,but it is difficult for real-time detection diagnosis and to calculate design specifications such as the false alarm rate.In this paper,it is proposed to extend the multi-domain physical system modeling language Modelica to describe a variety of failure modes model in the simulation model.And assumption-based truth maintenance system(ATMS) method...
Keywords:testability  failure diagnosis  model-based  assumption-based truth maintenance system(ATMS)
