网络控制系统研究综述

摘要

W ith the rapid developm ent of control, netw ork and com m unication technology, the netw ork control system (N C S) has becom e a hot research at hom e and abroad. Starting from the basic problem s existing in the system of netw ork control, this paper introduces the developing present condition, related technology and study result in detail on several aspects from netw ork delay, packet loss, inform ation dispatch, fault diagnosis and fault tolerant control. Finally it discusses the study direction in future.%　　随着控制、网络和通信等技术的飞快发展，网络控制系统（Networked Control Systems,NCS）已经成为国内外研究的热点。从网络控制系统存在的基本问题出发，从网络时延、丢包问题、信息调度、故障诊断与容错控制等几个方面详细的介绍了网络控制系统的发展现状、相关技术及研究成果，最后阐述了今后的研究方向。
