基于网络控制系统的建模方法综述

Overview of Modeling Method Based on Network Control System

随着计算机及网络技术的发展,控制系统中的各部件(传感器,控制器,执行器等)通过通信网络互连已然成为控制系统的发展趋势,但是通信网络为控制系统提供强大优越性的同时必然也带来了信息传输的不确定性,给控制系统的分析和设计增加了难度。因此基于在通信网络中不确定时延和丢包问题,文章探讨了其建模方法,为进一步的系统分析和设计奠定了基础。

With the development of computer and network technology,the communication network interconnection（sensors,controllers, actuators,etc.）has become a trend of the control system.However,the communication network provides a strong advantage for the control system,but also brings the uncertainty of information transmission.Therefore,based on the problem of uncertain time delay and packet drops in the communication network,this paper discusses the modeling method,which lays the foundation for the further analysis and design of the system.
