控制系统故障检测与诊断技术的最新进展

对故障检测与诊断(FDD)技术在控制领域的最新进展进行了综述,内容主要包括三类基本方法,即:基于解析模型的FDD、基于信号处理和基于知识的故障检测与诊断方法。重点评述了近年来发展起来的信息融合方法、多Agent方法、鲁棒故障检测、网络控制系统的故障诊断等。最后介绍了故障检测与诊断技术在控制系统中的若干应用成果,并指出尚待解决的主要问题和值得进一步研究的方向。

Survey on fault detection and diagnosis for control systems

The new development of fault detection and diagnosis(FDD) for control systems is surveyed,which consists of the main three categories: analytical model-based approach,signal processing based approach and knowledge-based approach.The recently developed methods such as information fusion,multiagent approach,robust FDD,the fault detection and diagnosis for networked control system are extensively reviewed.Some typical application results of fault detection and the diagnosis are given,and open issues on FDD are also pointed out.
