基于组态软件和Matlab的系统实时仿真平台设计

Design of Real-time Simulation Platform for Control System Based on Configuration Software and Matlab

设计了一种基于力控组态软件、Matlab、VC++的控制系统实时仿真平台。该平台用Matlab建立被控对象模型,用力控组态软件实现上位机图形界面,用VC++编写控制算法模拟实际控制器。三者之间通过DDE协议完成通信。该方法弥补了试验条件的不足,为系统稳、动态性能分析提供了方便、快捷的实现途径。将该平台应用于压力无关型变风量空调末端控制仿真,实验结果验证了其可行性。

A real-time control system simulation platform based on Force-control,MATLAB and VC＋＋ was introduced.In this platform,the model of the controlled object was established using Matlab,user interface was established using Force-control,and the controller of system was programmed using VC＋＋.These three parts connected through DDE protocol.This method made up the disadvantages of ground test conditions and facilitated the analysis of steady and dynamic performance of control system.The platform was used to a pressure-independent Variable Air Volume Air-Conditioning Terminal Unit control simulation,and the experiences prove that this platform is feasible.
