摘要
介绍了无线网络控制系统出现的背景,综述了无线网络控制系统的研究内容及现状。无线网络控制系统是基于无线网络的分布式控制系统,它融合了控制技术、计算机技术、网络技术与通信技术,已成为控制界的热点研究之一。针对无线网络控制系统中存在的随机时延和数据丢包,讨论了系统的建模问题,分析了目前的研究现状,并总结了国内外在无线网络控制系统研究过程中所提出的方法和取得的成果,提出了有待进一步解决的问题及以后的研究方向。
The background of wireless networked control systems is introduced, and the contents as well as states of research are surveyed. Wireless networked control system is a distributed control system based on wireless network, It is a combination of control, computer, network and communication technology, and becomes a hotspot in the control field, Considering the random delay and data loss in wireless networked control systems, the problems of system modelling are discussed. Then the actual states of recent research are analyzed, and the acquired methods and fruits of wireless networked control systems at home and abroad are summarized. Finally, some problems waited for more solution and the future directions are proposed.
