基于模糊层次分析的柴油机智能故障诊断

Fuzzy AHP-based intelligent fault diagnosis for diesel engine

针对柴油发动机故障多,且具有模糊性和复杂性的特点,设计了基于模糊层次分析的智能故障诊断系统.以柴油机起动系统为例,构建了故障层次模型,并采用三角模糊互补判断矩阵来表示各故障因素的可能性,结合多Agent技术,建立了具有自学习、自修正能力的智能故障诊断系统.

Aim at the fuzzy, complex and multiform characteristic of the diesel engine fault, a kind of fuzzy analytic hierarchy process-based intelligent fault diagnosis system was put forward. Taking starting system of diesel engine as an example, the fault hierarchy model was established, and the possibility of the fault factors was represented by used the experts＇ judgment matrix of the triangular fuzzy number, and an intelligent fault diagnosis system with self-study and self- modification was established based on multi- Agent.
