| 摘 要： | 网络控制系统（Networked Control Systems：NCSs）是指控制系统信息经由网络传输的控制系统。NCSs的故障检测与诊断（Fault Detection and Diagnosis，FDD）是保障系统安全稳定运行的关键技术之一。而网络将其优势带人控制系统的同时，也带来了时延、丢包等网络传输问题，这些问题给NCSs的控制和故障检测与诊断带来了新的困难。在总结了现阶段NCSs故障检测与诊断中处理网络诱导时延、丢包、不确定性以及系统非线性的理论和方法的研究成果后，并对今后研究提出了展望。

| Abstract: | Networked Control Systems(NCSs) are the control systems in which information of the control systems is transferred through the network.It is the key technology for safe and steady operation of NCSs to detect and diagnosis the faults of NCSs.With the advantage of the network,some problems,such as the network-induce delay,packet dropouts,are also introduced into NCSs.Because of these problems,some new difficulties are introduced into the controlling and fault detection for NCSs.In this paper,it is introduced that how to handle the network-induce delay,packet dropouts,uncertain and nonlinear factor in fault detection for NCSs,and besides the prospects of the future research for fault detection for NCSs. |
