【摘要】 网络控制系统是控制科学、计算机及网络技术的综合应用。网络资源的竞争及网络时延赋予传统的控制理论和方法新的含义和研究内容,对网络控制系统调度的研究是其中重要内容之一。本文在控制网络性能及协议层调度前人已有成果的基础上分析了网络控制系统在应用层上的调度算法,并在搭建的虚拟平台上对多任务的网络控制系统调度进行了仿真,通过仿真详细论述了RM算法和EDF算法对于网络控制系统性能的影响,表明了在网络资源竞争激烈的情况下,EDF调度算法在网络控制系统中的重要意义。论文还讨论了反馈控制实时调度算法,并对其在网络控制系统中的应用进行了探讨。

【Abstract】 Networked control systems are integration of controlling science, computing science and networking technology. The competition of network resource and network delay bring traditional control theories and methods new meanings and research directions, one important proportion of which is network scheduling. Based on existent results on control network performance and scheduling in protocol layer, the paper analyzes the scheduling algorithm of networked control systems in application layer, and structures multi-task networked control systems for scheduling simulation in virtual platform. Via the simulation, it is discussed how RM algorithm and EDF algorithm influence the performance of networked control systems, and presented the significance of EDF scheduling algorithm in networked control systems. Besides, the paper studies feedback-control real-time scheduling algorithms and their application in networked control systems.
