网络化控制系统是通过网络形成的反馈控制系统,具有资源共享、接线少、易于扩展维护及可靠性高等优点。TrueTime工具箱是针对网络化控制系统开发的一个基于Matlab/Simulink的联合仿真平台。以火电厂典型热工过程控制系统为例,利用TrueTime工具箱网络模块和计算机内核模块,将其与Simulink中的常用模块相连,设计了基于TrueTime工具箱的网络化控制系统仿真模型,并通过大量仿真研究证明了针对典型热工过程网络化控制系统方案的可行性和有效性。
The networked control system with a feedback control system has the advantages of resource sharing,few cables,easy to extend and high reliability,etc.The Truetime toolbox based on Matlab/Simulation is an integrated simulation platform aimed at establishing a networked control system.This paper takes typical thermal process control system for example,a simulation module of networked control system based on TrueTime toolbox is designed,which uses the network module and computer kernel module of the TrueTime toolbox and it is joined with the common modules in the simulink.The simulation studies show the feasibility and efficiency of the control strategy for typical thermal processes control system.
