Real-time control system based on MATLAB and PCAuto via OPC technology

MATLAB provides us plenty toolboxes to develop kinds of advantage control algorithms, and PCAuto known as a famous SCADA configuration software is widely used in industry due to its powerful data acquisition function, strong real-time database system and excellent graphic human-machine interface. In this paper, the communication between MATLAB and PCAuto based on OPC (OLE for process control) technology is presented. To test the performance of the communication, a realtime improved single neuron adaptive PID liquid level control system is realized. The control process and results verify that the data exchanging is very efficient and reliable. The research of this paper presents a new approach to apply advantage control theories to real-time control system.
