Simulation and researching of control system based on Matlab and WinCC

In combination of the powerful capability of engineering computing of MATLAB and the virtual interface of WinCC, the serial communication between WinCC and Matlab is designed and realized by using dynamic data exchange(DDE). As the communication interface of client Matlab and Server WinCC, DDE implements better communications between heterogeneous systems. This paper describes in detail its methods and concrete steps, 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.
