摘　　要：针对网络化控制系统存在随机时延、丢包、异步等问题,在分析网络控制系统不同数学模型基础上,详细介绍了故障诊断与容错控制的常用方法:即基于信息调度模型的方法、基于时延模型的方法、基于T-S模糊模型的方法.并相应地分析了每种方法的原理及其优、缺点.另外,还对近年来常用方法的最新发展结果进行了总结分析.最后指出该领域有待进一步研究的若干问题和发展趋势.The network-induced delay, packet dropout, asynchronous and other peculiarities of networked control systems （NCS） may degrade the performance of closed-loop systems. We have to develop new theory and techniques for control systems that operate through data network. This paper reviews the main ideas and results on fault diagnosis of NCS, including the fault diagnosis for NCS with information scheduling, fault diagnosis approaches based on the simpli- fied time-delay system models, and the T-S fuzzy model. The further problems to be studied in this field and the development trends are also proposed.
