ABSTRACT:In combination of the powerful capability of engineering computing of MATLAB and the virtual interface of AdvanTrol-Pro, the serial communication between AdvanTrol-Pro and Matlab is designed and realized by OPC technology. As the communication interface of client Matlab and Server AdvanTrol-Pro, OPC implements better communications between heterogeneous systems. This paper describes in detail its methods and concrete steps, and algorithm is verified in the control system of the distillation column in the laboratory the purpose of separately constructing object model and controller can be reached, thus effective simulation platform of theoretical research and design of control systems is provided.

Keywords:Distillation column, PID, OPC, MATLAB
