摘要
网络控制系统是集控制、计算机和网络通信等多种技术于一体的复杂系统,该系统的复杂性给它的分析和设计带来了严峻的挑战,网络控制系统的仿真研究工具就显得尤为重要。以火电厂典型热工系统为被控对象,构建了一个热工过程网络控制系统模型,利用Truetime工具箱,研究了网络传输速率、采样周期、数据丢包率、时延、扰动和通信模式6种因素对系统性能的影响,并给出了仿真曲线和相应的结论。
Network control system is a complex system integrated with control,computer,network communication and other technologies,whose complexity brings the severe challenges to the analysis and design,so the simulation tools of network control system is particularly important.In this paper,choose the typical thermal system of thermal power plant as the controlled objects,and build a model for network control system of thermal process,then using Truetime toolbox,study the effects that the six factors such as the network transmission rate,sampling period,data packet loss rate,delay,disturbance and communication mode bring to the system performance,finally provide the simulation curve and the corresponding conclusions.
