| 摘 要： | 网络控制系统(NCS)是一种新型计算机控制系统,通过工业网络实现控制单元之间的数据交换,但这也给控制系统带来了时延等问题。开发了一种基于Matlab和OPC技术,以校园局域网为媒介的虚拟NCS实验平台,利用西门子S7-300PLC作为实验平台的服务器,用Matlab OPC Toolbox工具箱提供的OPC技术实现OPC服务器与客户端的网络通信,实现了对象模型和控制器在两台计算机的分离,从而获得网络化控制系统仿真平台,为高级控制算法的研究和验证提供了良好的实验平台。

| Abstract: | The networked control system(NCS) is a new kind of computer control systems.Though industrial networks different control parts communicate with each other,which leads new problems to control systems such as time delay and scheduling.Based on Matlab and OPC technology,and mediated by campus LAN,Siemens s7-300 PLC is used as experimental platform of the server,the OPC technology,provided by OPC Toolbox of Matlab,is used to achieve OPC server and client network communication.This method realizes the separation of the plant model and controller on two computers,thus obtaining a network control system experiment research platform for the study and validation of the advanced controlling algorithms. |
