基于组态王、EXCEL和MATLAB的液位控制仿真平台研究

摘要

考虑到组态王软件具有强大人机界面和通讯的优点,MATLAB软件可以实现复杂控制系统建模和分析等特点.基于结合两者软件优点的目的,本文使用Simulink软件搭建双容水箱串级PID控制模型,并提出了使用其workspace工作空间与EXCEL数据库通过DDE (Dynamic Data Exchanged动态数据交换)通讯协议进行实时数据通讯,同时组态王软件完成动画监控界面和PID控制参数设置,实现了组态王、EXCEL和MATLAB 3种软件构建水箱液位控制的虚拟实验平台.实验表明,该仿真平台充分利用各个软件的优点,为复杂控制系统学习和应用搭建了一个有效的实验平台.%Taking into account the Kingview software has a powerful man-machine interface and the advantages of communication,MATLAB software can achieve complex control system modeling and analysis and so on.Based on the purpose of combining the advantages of the two software,this paper uses Simulink software to build the cascade PID control model of the double-volume water tank,and proposes a real-time data communication using DDE (Dynamic Data Exchanged),At the same time,Kingview software completes the animation monitoring interface and PID control parameter setting,and realizes the Kingview,EXCEL and MATLAB software to construct the virtual experiment platform of the tank level control.Experiments show that the simulation platform makes full use of the advantages of each software,and builds an effective experimental platform for complex control system learning and application.
