网络控制系统中信息调度的研究进展

由于网络带宽的限制以及控制系统的时限要求，网络控制系统的性能不仅取决于控制算法的设计，而且取决于网络信息的调度，以实现各个网络节点资源分配。文中综述了网络控制系统中信息调度的研究进展，主要内容：首先比较了单处理器的任务调度与网络控制系统的信息调度；介绍了单处理器的RM和EDF两种实时调度算法以及多处理器的调度算法；讨论了调度的单独设计和调度与控制的共同设计；最后探讨了若干待解决的问题及发展趋势。

Study and Progress of Messages Scheduling of Networked Control Systems

With the limit of network hand width and deadline requires on control systems,the performance of networked control systems not only depend on the design of control algorithm but also on the message scheduling,in order to assign network resources among the nodes. Summarized the research progress of message scheduling of networked control systems, compared message scheduling of networked control systems with task scheduling of single processor; introduced RM and EDF real-time scheduling algorithms; discussed message scheduling without considering control and scheduling and control co-design; lastly, discussed some problems that were needed to resolve and its developing trend.
