提出模糊知识的表示方式, 并以模糊知识建立故障诊断专家知识库。设计了基于模糊推理的规则竞争的消除策略, 诊断出故障原因和与之匹配的动作代码, 保留推理轨迹, 实时更新知识库, 用于在线故障诊断和自主学习。
This paper presents the building of the expert knowledge system for fault diagnosis based on fuzzy inference.Using the elimination strategy for the rules′ competition based on fuzzy inference, the fault diagnosis system with the causes and their corresponding action code and the original reasoning paths in the process, and the real-time updated knowledge will be helpful for on-line fault diagnosis and self-learning.
