摘要
针对网络控制系统(NCS)中网络带宽等网络资源受限制的情况,对目前NCS信息调度的研究现状进行了综述.首先介绍了NCS的背景和基本概念,阐述了网络的引入带来的各种影响.然后研究了NCS的动态特性,对现有的信息调度策略和调度方法进行了总结与分析.进一步分析了在资源受限时如何进行有效的信息调度以保证较高的网络服务质量QoS(Quality ofService)和较好的控制品质QoC(Quality of Control),对一些控制与调度协同设计的研究进行了说明.最后,结合前面的研究分析,讨论了该领域今后进一步的研究方向.
According to the case that network resources such as bandwidth are always constrained, the paper has an o- verview on the open literature of message scheduling in Networked Control Systems. The background and basic concept of NCS are firstly introduced, and so are a variety of effects caused by introducing the networks. Then, dynamic charac- teristics of NCS are studied, existing scheduling strategies and scheduling algorithms are summarized and analyzed. Further studies on effective scheduling to guarantee high Quality of Service of network and Quality of Control with resource constraints are conducted, co-design of control and scheduling is also considered. In addition, on the basis of the previous analysis, future work in the further study is discussed.
