基于T-S模糊故障树的系统故障诊断研究

Research of the system fault diagnosis based on T-S fuzzy fault tree

针对传统的故障树分析法在故障诊断中存在的缺点和不足,文中将模糊理论运用到故障诊断中,提出基于T-S的模糊故障树的故障诊断法。介绍了T-S模糊模型及算法,建立了诊断系统的故障库和推理机。使设备操作和维修人员可及时发现故障,降低系统故障率,提高了保障的能力。

Aiming at the existing shortcomings and the insufficiencyof the traditional fault tree analysis in fault diagnosis, this paper applyes blurred theory to the fault diagnosis and proposes the fault diagnosis based on T-S fuzzy fault tree. The T-S fuzzy model and algorithm has been introduced and the fault library and reasoning machine of the diagnosis system has been established in this paper. Thus, the equipment operation and maintenance personnel can timely fain faults, and the system failure rate will be reduced and the support capacity can be improved as well.
