基于模糊专家系统的故障诊断方法研究

Research on Fault Diagnosis Method Based on Fuzzy Expert System

随着汽车发动机技术的发展,汽车的安全性、可靠性和操控性得到了极大的改善,使汽车的复杂程度越来越高。为此,开发了基于汽车发动机故障诊断专家系统,介绍了系统的基本结构及其开发方法,重点描述了模糊知识的表示、知识的管理以及推理机制的构成。经过多次使用证明,该专家系统具有非常高的使用价值。

Following with the development of automobile engine, the safetibility, reliability, and controllability of automobile are greatly improved, which make its structure become more and more complex. Hence, the fault diagnosis expert system based on automobile engine is developed. The construction and development method of vehicle engine fault diagnosis fuzzy expert system are introduced in this paper. The fuzzy knowledge expression, management of knowledge and the inference mechanism forms have been described to the focal point, Passing uses this expert system of proof to possess very good practical value many times.
