融合异步多率采样传输和采样控制的大规模网络系统能控性研究

随着通信、控制和计算机的发展与融合，网络系统囊括大量通过信息传输进行相互作用的自主节点，这些节点一方面受通信机制的限制，传输的往往是采样信号；另一方面节点的控制输入也是通过计算机实现的采样控制。鉴于采样传输和采样控制是网络互连和计算机控制环境下系统实现的必然需要，本项目围绕大规模复杂动态网络系统在采样传输和采样控制下的能控性开展研究，针对不同节点采样传输时刻和采样控制时刻的非同步、采样周期的多频率，建立传输多率采样网络系统、控制多率采样网络系统和广义多率采样网络系统模型；研究传输采样周期、控制采样周期、网络结构和节点动力学对大规模网络系统能控性的影响，给出能控性判据；联合设计无病态采样传输和采样控制方案保证网络系统的能控性。本项目的完成将为融合采样传输和采样控制的网络系统控制奠定理论基础，为深度融合信息、计算与控制的工业网络系统运行提供一些技术实现保障和指引。

With the development and integration of communication, control and computing technologies, networked systems usually contain a large number of autonomous nodes that interact through the transmission of information. On the one hand, the information transmitted between nodes is typically sampled data, which is limited by the communication mechanism. On the other hand, the control inputs of the nodes are also sampled-data control implemented by the computer systems. In view of the fact that the sampled-data transmission and the sampled-data control are inevitable needs for the system realization in network interconnection and computer control environment, this project will study the controllability of large-scale complex networked system under sampled-data transmission and sampled-data control. In view of the non-synchronous sampling time and multi-rate sampling period through discrete-data transmission and digital control among different nodes, a transmission multi-rate sampling networked system, a control multi-rate sampling networked system and a generalized multi-rate sampling networked system model will be established to study the effects of the sampling period in transmission, the sampling period in control, the network structure and the node dynamics on the controllability of a large-scale networked system. Moreover, non-pathological transmission sampling and control sampling schemes will be jointly designed to maintain the controllability. The completion of this project will lay a theoretical basis for the control of networked systems with sampled-date transmission and sampled-data control, and will provide some technical assurances and guidelines for the operation of industrial networked systems with comprehensive integration of information, computing and control technologies.
