PLC-based Temperature Fuzzy Control System Design Research

The paper introduced a PLC-based temperature fuzzy control system design method and elaborated the basic theory of PLC and relevant PLC engineer design through electric heating temperature control. The paper will design a fuzzy controller based on the Siemens programmable control, targeting at the features of temperature control. It adopts Profibus-DP field bus to establish a field control layer and then construct a supervision and management layer based on industrial Ethernet. Finally, it realizes fuzzy control of temperature, regarding furnace temperature as the control object.
