中文摘要： 本项目针对网络控制系统中存在的传输受限现象进行建模与控制器设计。主要研究了系统传输过程中存在的网络时滞和数据丢包现象，给出了稳定性分析和控制器设计。重点讨论了模型存在非线性扰动时的处理方法。项目组同时还研究了线性不确定广义时滞系统新的时滞相关鲁棒稳定性判据和镇定方法，通过选取一个新的Lyapunov-Krasovskii 泛函给出了状态反馈控制器设计算法，也给出了线性不确定广义摄动系统的鲁棒性能分析和控制器设计，保证相应的闭环系统对所有容许的不确定性参数是正则、因果和鲁棒稳定的。本项目为基础研究项目，为1年期小额资助，项目成果在理论与方法上均有所创新。在国内外核心刊物与国际国内会议上共发表（加录用）论文10篇，SCI待检索1篇，EI检索9篇，培养硕士研究生2名。

英文摘要： This project aims to the modeling and the controller design of Networked Control Systems(NCSs), whose emphasises are focused on the stability analysis and controller design with communication constraints in the transmission process of NCSs between the nodes, such as network-induced delay, packet dropout. The problem of stabilization for a class of uncertain NCSs with nonlinear perturbation is discussed. On the other hand, some new results of delay-dependent robust stability and stabilization for uncertain linear singular time-delay systems are presented by using a new Lyapunov-Krasovskii functional. And the problem of robust H-infinity control for a class of uncertain linear time-delay singularly perturbed systems is considered, which guarantees the singular time-delay system to be regular，impulse free and robustly stable for all admissible uncertainties．As a basic research project, it makes innovations in both theory and method. Under the support of this annual project, 10 papers have been published (or in press) in the international journals and conferences among which 10 papers have been indexed (or to be indexed)by SCI and EI, 2 graduate students in this project team have been trained.
