中文摘要： 基于信道传输容量有限的正常系统的网络控制问题已有许多研究成果。尽管广义系统较正常系统更广泛，且有众多的工程应用，但对于基于信道传输容量有限条件下广义系统的网络控制问题研究成果很少。本项目分析信道传输容量有限或信道传输率受限条件下被控对象为广义系统的网络远程检测和控制等问题，采用编码-解码方法给出相应的广义网络系统的可检测性和可镇定性，得到相应性质的充分或必要条件。同时对于具有非线性扰动的广义非线性网络系统，得到鲁棒可镇定性和鲁棒可检测性的判据。此外，得到信道容量、网络诱导时延以及数据包丢失对广义网络控制系统的稳定性的影响，给出广义网络系统的确定性最优控制器和随机最优控制器的设计。建立广义网络系统的基本理论框架，进一步丰富广义系统和网络控制系统的基本理论。最后开发出相应的仿真软硬件，为建立网络化和远程化的新型控制系统提供理论依据和技术支撑。

英文摘要： Numerous results on the networked control problems for normal systems via a limited capacity communication channel have been found in the literature. Although singular system contains the normal system as a special case and has many engineering applications, few results on the networked singular systems with limited communication capacity have been reported. In this proposal, the detection and control problems for singular systems via a limited communication capacity or with data transmission rate constraint are studied. Using code-decode approach,the concepts of detectability andstabilizability for networked singular system are proposed and corresponding sufficient or necessary conditions are studied. Some necessary or sufficient conditions are presented for robust detectability and robust stabilizability of networked singular system with nonlinear perturbation. In addition, the effects of communication capacity,network-induced delay and data packet dropout on the stability of the networked singular system are considered, optimal controller and stochastic optimal controller are presented, respectively. The basic theoretical framework for the networked singular system is established, which will enrich the basic theory of singular system and networked control system. Software/Hardware for system simulations is developed, which will provide theoretical basis and technical support for this novel type of networked and remote control systems.
