Real-time intelligent control of liquid level system based on MCGS and MATLAB

Intelligent control has been greatly developed and theoretically researched, but it is usually limited to the off-line simulation research. In order to put advanced control algorithms into practice, using a reliable OPC (OLE for Process Control) technology to connect the field process and control equipment, and to realize the data reading in real time, the specific implementations way to achieve real-time control of field devices by combining with the powerful operation ability of MATLAB and the advantage of real-time data collection and monitor of MCGS configuration software. In this paper, we apply this way to PCS-C type process control device, using Fuzzy PID control algorithm to achieve double-tank water level control, which can achieve good control effect.
