摘要
基于定性模型的故障诊断方法,利用定性模型描述系统结构和定性地预测系统行为,并通过与实际行为进行比较,可推理得到系统的故障诊断结果。详细介绍了基于定性模型故障诊断方法的诊断机理、建模方式及优缺点。此外,还概述了该方法的研究与应用现状及发展趋势。
The qualitative model-based fault diagnosis approach can depict the system configuration in qualitative model, and get the predicted behavior qualitatively. The system fault can be diagnosed by determining the differences between the model, of an artifact and the artifact itself. This paper investigates the diagnosis mechanism, system modeling, advantages and disadvantages of the qualitative model-based fault diagnosis approach. Its progress, application, and developing trend are also addressed.
