摘要
网络控制是计算机、通信技术和控制技术融合发展所形成的一个新领域.在综述网络控制系统研究现状的基础上,指出网络时延特性是影响系统性能的关键因素.重点分析了时延的构成和不确定性,结合数据特征探讨了几种与时延特性密切相关的数据传输技术和常用协议的技术构成.最后给出了网络控制系统的主要研究内容和发展趋势展望.
Networked control system (NCS) is a new study field that integrates computer, communication (technology) and control technology. Based on the survey status of networked control systems, it is presented that (delay) characteristic is a key factor to determine the system performances. And the components and uncertainty of the network delay are analyzed. Combined with data characteristics, several kinds of data transmission techniques (closely) related with delay character are discussed and the technique compositions of the usual network protocols are presented. Finally, the principal research directions and the development tendency of NCS are proposed.
