【摘要】 网络化控制系统与传统结构的控制系统相比具有许多优点,但经网络传输的控制信号所带来的随机时延、丢包、异步等问题会影响闭环控制系统的性能,因此需要发展可在网络环境工作的系统的控制理论和技术。故障诊断与容错控制对于控制工程实践特别是对安全性有严格要求的控制系统是十分重要的。近年来,我们较为系统地开展了网络化控制系统故障诊断与容错控制的研究工作从而可对故障诊断的主要研究结果进行概述。更多还原

【Abstract】 Networked control systems have many advantages compared with traditional control systems,but at the same time,the network-induced delay,packet dropout,asynchronous and other peculiarities of networked control systems may degrade the performance of closed-loop systems.We have to develop new theory and techniques for control systems that operate through data network.Fault diagnosis and fault-tolerant control are very important issues for practical control systems,particularly for safety-critical systems.We investigated the fault detection and fault-tolerant control theory and technology for networked control system in recent years.This paper summarized our main results on fault diagnosis of networked control systems.更多还原
