Temperature Control System of Resistance Furnace Based on Fuzzy-PID Leijianjun1 zhuhua1 Gudeying2 1(Electric Department of Liaoning Technical University Liaoning Fuxin 123000) 2(Automatic Department of Northeastern University at Qinhuangdao Hebei Qinhuangdao) Abstract:This article applies Fuzzy-PID arithmetic to temperature control system of resistance furnace, and introduces the design of Fuzzy-PID controller, hardware circuit and software structure. The system realizes gathering and control of temperature. The merit of the whole system is small, low cost; the function is strong and intelligent. The running effect is also satisfactory.
