中文摘要： 网络化控制系统是目前控制界的一个热点研究课题，然而，传统的网络化控制系统控制器集中计算、信息处理功能没有完全分散的问题仍然存在。分布式无线网络化控制系统可望有效解决传统网络化控制系统存在的不足，但是，在将无线网络技术应用于控制系统的过程中产生了新的问题，如网络的拓扑结构、无线信道容量约束、节点的能耗约束等都会对控制系统整体性能产生影响。现有的分布式无线网络化控制系统理论还远未成熟。本项目从如何建立网络拓扑条件与系统稳定性之间的关系出发，深入研究能耗约束下的信息传输调度与控制协同设计问题，以及如何检测网络节点在运行过程中可能发生的异常行为。提出结合网络特征参量的网络化系统综合建模和分析方法，建立特征参数和系统性能指标间的定量关系。旨在提出分布式无线网络化控制系统的建模、分析、设计以及异常检测等相关方面一整套具有创新性的理论与算法。最后，通过移动机器人实验平台验证理论结果的有效性。

英文摘要： Networked control systems (NCSs) has been a hot research topic in the control society. However, problems such as centralized computation and processing of controller in the conventional NCSs still exist. Distributed wireless networked control systems (DWNCSs) have the potential to effectively solve the aforementioned problems in the conventional NCSs. However, the introduction of wireless networks to the feedback control loop brings upon new problems in system design, and the overall system performance may be affected by a variety of issues caused by the wireless network, such as the network topology, capacity constraint of the wireless channels, power constraint of the sensors, and so on. Corresponding theory on the DWNCSs is still far from mature. The project starts from how to establish relations between the topology condition of wireless networks and stability of the control systems, the co-design problem of the message transmission scheduling and controller gain with energy constraint in wireless sensor nodes as well as how to detect the possible abnormity of the network nodes will also be investigated. The project aims to give novel modeling and analysis methods for establishing relations between the network parameters and system performances. The project focuses on presenting a bunch of innovative theorie
