In recent years, fuzzy PID control application in many the success, fuzzy PID control applied to control system design, need not know is accurate mathematical model for many cannot be established mathematical model of complex systems can gain better control effect, also can simplify system design, therefore, in the resistance furnace temperature control system, the fuzzy PID control becomes better choice. This paper discusses the application of fuzzy PID control system, control theory of resistance furnace is introduced first exhaustive PID control and fuzzy control theory of knowledge, and proposed in this foundation with PID and theory of fuzzy PID control scheme for temperature is established, based on the resistance furnace temperature of simple mathematical model of fuzzy PID controller, and then, by comparing the simulation proves its feasibility.
