摘　　要： 大型复杂系统投资大，维修费用高，而且停机损失巨大或事故后果严重，因而其故障诊断技术越来越受到重视。本文系统地介绍了复杂系统故障的特点及其诊断原理，在此基础上，对大型复杂系统故障诊断的信号处理技术、故障原因识别技术及其应用作了评述，并对故障诊断的发展作出了展望。 The investment and the maintenance cost of complex system are large, the losses of stopping a machine are heavy or the accident consequences of complex system are serious. So fault diagnosis of complex system has become more and more importan. This paper of fers an overview of fault character, theory and applications for fault diagnosis of complex system, includes the technology of fault signal processing and fault cause finding. Future development of fault diagnosis has also been discussed.

关 键 词： 复杂系统 故障诊断 信号处理 综述
