【摘要】 网络控制系统是控制科学和计算机网络及通讯技术的综合应用。随着国际互联网在全球的飞速发展，网络中存在的使网络控制系统性能下降、甚至不稳定的大时延日益受到研究者的重视。本文首先介绍了大时延网络控制系统的基本概念，分析了网络控制系统中时延的产生原因，在大时延网络控制系统中应用了Smith控制方法和比例微分控制方法。其次将基于事件驱动的控制方法引入到网络控制系统中，设计了基于事件驱动的网络控制系统控制器。最后实验结果表明本文的方法是有效的。更多还原

【Abstract】 Networked control systems are integration of controlling science, computing network and communicating technology. While Internet technology is developing quickly, large time delay in the network may cause the declining of performance and even instability in networked control systems that is attracting the interest of researcher. Firstly the basic concept of networked control systems with large time delay is introduced in this thesis, the reason of time delay in networked control systems is analyzed. Smith controller and PD controller is used to networked control systems with large time delay. Secondly, event-based method is introduced to network control systems, an event-based controller is designed and implemented. At last experimental results validate the proposed approach.更多还原
