Design of Fuzzy Control System for Tank Liquid Level Based on WinCC and Matlab

In the industrial control area, WinCC is widely applied in industrial production process of real-time monitoring control and has become one of the important configuration software. But it is still unable to realize complex control algorithm with shortage of programming language. While Mat lab can deal with large amounts of data with high efficiency with its toolbox and Simulink simulation environment, complex control algorithm can be realized through the research on the model and simulation of the control system. Thus, in this paper, they are combined organically under the background of level control of the tank, and a real-time fuzzy control scheme based on OPC communication technology is put forward. Finally intelligent control of the tank level is realized and its effectiveness is verified as well.
