中文摘要： 网络化控制系统是当前控制领域的研究热点和前沿课题。现有的网络控制系统的理论结果大多是基于线性控制方法展开研究的，很少考虑存在模型不确定性、外界扰动以及未知非线性情形下的非线性控制器设计问题。滑模控制对匹配的外界扰动、模型不确定性和非线性具有完全的鲁棒性，研究网络通讯情形下滑模控制系统的分析与设计问题具有重要的研究意义和应用前景。另一方面，网络数据通讯中的传输延迟、数据丢包、量化误差等问题给传统的滑模控制理论技术提出了新的困难和挑战。本项目将采用奇异摄动系统理论、Delta算子理论等方法对网络诱导因素进行建模和处理，同时结合滑模控制理论和数字控制理论,对网络环境下的复杂非线性动态系统的滑模控制器设计问题开展深入分析和研究。本项目基于前期的研究工作基础，旨在建立一套关于网络控制系统的滑模变结构控制器设计方法的较为完整的理论体系,提高网络控制系统和滑模控制理论在工程实践中的应用能力。

英文摘要： Networked control system is one of the most significant research topic in international control theory area. However, the obtained results in the existing literatures are mostly focused on linear control design approach, and there is few work on nonlinear controller design with model uncertainty, external disturbance and unknown nonlinearity being taken into consideration. It is well known that sliding mode control is robust to the matched disturbance, model uncertainty and nonlinearity, and the design and analysis of network-based siding mode control possesses a significance and extensive application in practical engineering. On the other hand, network-induced transmission delay, data packet losses and quantization error bring difficulty and challenge to traditional sliding mode control theory. Due to this fact, this project will adopt singular perturbation theory, Delta operator theory to model and deal with these network-induced issues. Combining with sliding mode control theory and digital control theory, we analyze and investigate the problem of network-based sliding mode control for complicated nonlinear dynamic systems. Based on our previous research work, the aim of this project is to build a systemic and complete theoretical framework for sliding mode controller design of networked control systems, and improve the applicability of networked control systems and sliding mode control in practical engineering.
