Abstract :
Limited by the matrix operation ability of normal control CPU (e.g. MCU, PLC and so on), the realization of fuzzy control always via the way of ldquocalculate offline and inquire onlinerdquo. Applications and practices have proved that such a realization method brings system steady-state error, and limited the application range of fuzzy control. Based on the study of FC theory and the analysis of Mamdani fuzzy reasoning from geometrical meaning, a real-time fuzzy controller can be realized on PLC is designed and used in air-cushioned headbox control system based on S7-300 PLC. The results show that the real-time FC can avoid the steady-state error effectively and improve the controllability further.
