基于T-S模糊故障树的某装备测控设备故障诊断研究

摘要

In traditional the limitation of the method of fault tree analysis, the T-S fuzzy model based on the method of fault tree analysis is explored. The method makes a deal with the fuzzy fault tree information ability . This analysis method does not require accurate understanding the mechanism and parts of the fault probability, solve the system failure and the uncertainty of the fault mechanism. Finally, with the equipment monitoring and control equipment failure examples of analysis of monitoring and control equipment fault are given.%针对传统故障树分析方法的局限性,探讨了基于T-S模糊模型的故障树分析方法.该方法使故障树有了处理模糊信息的能力.该分析方法不需要精确了解故障的机理和部件的故障概率,解决了系统的故障和故障机理的不确定性问题.最后结合装备测控设备故障,给出了测控设备故障的分析实例.
