中文摘要： 通过网络实现闭环控制越来越受到国际学术界的重视。网络控制系统中通常采用的单包传输和基于等周期的时间驱动传输策略对于网络资源受限的具有多传感器和执行器的大规模系统不再适用。针对资源受限网络环境下的大规模系统，本项目从三个方面进行深入研究：1）为达到期望控制性能而占用较少网络资源的目标，研究基于"离散采样，事情驱动传输"的必要性通讯策略；2）基于大规模系统空间分布性特征，研究利用子系统本身和直接相连子系统信息并嵌入必要性通讯策略的通讯阈值误差依赖的分布式控制模型；3）基于已有通讯策略与控制算法分别设计的问题，研究通讯策略与分布式控制协同设计方法。基于提出的理论方法与技术路线，针对并联倒立摆等复杂大规模对象进行网络与控制协作实验，开发出适应大规模系统网络控制的远程控制模块和相应的控制与通讯软件，建立网络控制应用示范平台；在网络控制系统通讯策略、分布式控制、通讯与控制协同设计等方面提供有效方案。

英文摘要： Control over a communication network has attracted more and more interests in international academe.The general adopted time-triggered single-packet communication scheme in a networked control system is not suitable to a large-scale system (LSS), since LSS is spatially distributed and with multi-sensors and multi-actuators. For a large-scale system connected via a limited bandwidth network, the following three points will be addressed in this project: 1) necessary communication scheme with the characteristic of discrete sampling and event-triggered communication will being studied for saving the limited network resources and guaranteeing the desired control performance; 2) based on the spatially distributed characteristic of large-scale systems, a communication threshold-error dependent distributed control modeling will being constructed based on the information of subsystem itself and its' directly connected subsystems; and 3) since the performance of an NCS depends not only on the design of the control algorithms but also on the scheduling of the share network resources, separately considering the control and communication in the open literature will inevitably bring some conservativeness. To tackle this problem, the co-design between the control and communication will being carefully studied. Based on the pr
