摘要
介绍了网络化控制系统(networked control system,NCS)出现的背景,综述了NCS面临的基本问题和现状,整理了近年来NCS分析与综合方面的研究成果和最新进展.描述了NCS的模型、特点、时延、丢包、稳定性、网络调度等内容,归纳了现有的研究方法.对TrueTime和NS2等仿真工具做了比较详细的阐述.最后,论述了NCS研究中尚待解决的问题,展望了网络控制系统未来的发展前景.
The emergence background of hetworked control system （NCS） is introduced. The basic problems and research status in NCS are surveyed. The research achievements and advances of analysis and synthesis in NCS are presented. Such issues as model, characteristics, delay, packet dropout, stability, network scheduling of NCS are described. The present research methods are summarized. The simulation tools such as TrueTime and NS2 are particularly expatiated. Finally, the problems to be dealt with in NCS are pointed out and the future development directions in NCS are given.
