故障诊断技术的研究现状及展望

Status Quo and Prospect of Fault Diagnosis Theory

在阐释故障诊断技术内涵的基础上,详细介绍了国内外主要故障诊断技术的优缺点:单一的故障诊断技术有着各自的优缺点,难以满足复杂系统的故障诊断要求.讨论了当前故障诊断技术研究存在的主要问题:故障分辨率不高、信息来源不充分、自动获取知识能力差、对不确定知识的处理能力差等.最后,指出了目前和今后的主要研究重点和方向.

This paper explains the fault diagnosis theory and analyzes in detain the advantages and disadvantages of main fault diagnosis both at home and abroad.A single fault diagnosis techniques has its own advantages and disadvantages and can not meet the requirements of the diagnosis of complex systems.The paper argues that the main problems of the current fault diagnosis lie in low fault resolution,inadequate sources of information,low automatic acquisition of knowledge,inefficient treatment of the uncertain knowledge etc.It also addresses the current research priorities and orientations for future study in the field.
