Design of Fuzzy Control System of Air Compressor Based on PLC

In order to improve the automation level of coal mine air compressor,and automatically control the number of working air compressor in accordance with air pressure,this paper introduces the application of fuzzy control algorithm to establishing an automatic control system of air compressor.It adopts SIEMENS PLC as the core of control system,monitoring、controlling and managing the running process of air compressor and other equipments.The WinCC is used for configuration in upper computer interface,which can modify the parameter and display the varieties of the parameters,and realize remote control.The practice has proved that the system performance is reliable,and maintenance is convenient,which improves the productivity efficiency of coal mine impressively.
