中文摘要: 网络化关联系统的出现和发展体现了控制系统网络化、分布化以及节点智能化的发展趋势。然而,由于非理想网络状况和关联作用的影响,网络化关联系统的研究要比传统网络控制系统或关联系统的研究复杂得多。到目前为止,无论建模方法还是控制手段,都存在大量问题亟待解决。本项目基于混合触发机制策略研究网络化关联系统的分析与综合,所设计的混合触发机制结合了时间触发机制和事件触发机制的优点,能最大限度减少数据包的发送频率,缓解网络带宽受限带来的不利影响。在综合考虑网络、关联和混合触发机制相互影响的前提下,本项目将研究网络化关联系统的建模问题,分析系统的稳定性和其他性能,设计和优化系统的控制策略,并通过构建的网络化关联系统实验平台检验和完善得到的理论成果。本项目将揭示网络化关联系统的本质和特征,拓展传统网络化控制系统和关联系统的研究,提供基于混合触发机制的网络化关联系统的建模、分析和控制的新方法和新理论。

英文摘要: The emergence and development of networked interconnected systems show the trend of control systems being networked, distributed and node intelligentized. However, due to the synthesis effect of non-ideal network conditions and interconnections, research on networked interconnected systems is more complex than the research on traditional networked control systems or interconnected systems. Up to now, there still have been many unsolved problems in modeling and control of the systems. Based on the hybrid-triggering scheme, this project will study the modeling, analysis and control problems of networked interconnected systems. The proposed hybrid-triggering scheme combines the advantages of time-triggering scheme and event-triggering scheme, it can minimize data transmission frequency and then alleviate the burden of the network bandwidth. Considering the synthesis effect of network, interconnection and hybrid-triggering scheme, a more general networked interconnected system model is built and the corresponding stability analysis method and control synthesis technique are proposed. The obtained theory results can be proved and improved by the built networked interconnected system platform. This project will reveal the nature and characteristic of the networked interconnected systems and expand the study of traditi
