有线/无线异构网络控制系统性能分析及信息协处理

With the fast development of computer technology, network technology and control theory etc, the Heterogeneous Networked Control Systems (HNCSs) constructed upon wired network and wireless network integration platform had been a hot research issue in the field of special industrial applications. In this project, the first issue about correlation of network basic communication parameters and network performance parameter will be deeply studied. And the certain universality mathematical model of HNCSs will be described based on the detailed analysis of their evolution mechanism. Then the performance and design of HNCSs will be qualitatively described and quantitatively described. On this foundation, the second issue of its ultimate performance (such as asymptotic stability, robust stability) and emergent properties will be researched. The third issue about codesign strategy will be proposed to reduce the effects of communication uncertainties by using game theory in network bandwidth allocation and grey prediction in system control. At last, the hybrid network system platform will be constructed to show the efficacy and feasibility of the proposed methods. In conclusion, all the research work in this project lays an important foundation for the modeling, architecture, protocol conversion and measured application of industrial wired/wireless hybrid network system, and provides the experimental foundation and the theoretical support for networked control systems promotion.
