Abstract
With the development of industry．electric heating furnace is more and more widely used .Temperature is important parameter of electric heating furnace ．and the demand of temperature control is increasing. The traditional control method usually base on a precise mathematical model，nevertheless．for the electric heating furnace control system with the characteristic of non-linear,pure time-delay，large inertia．time-variation and unidirectional rising．It is difficult establish a precise mathematical model．It will appear steady-state error due to the complex algorithm and imperfect theory of fuzzy control Traditional PID control Call mostly meet the control demand for its maturity and easy comply，but its efficiency relies on its parameter-tuning And because of the conflict between quickness and the small temperature oversetting point,it probably can’t meet the control demand In this paper,fuzzy control and traditional PID control are combined．And fuzzy control rules are established basing on manual experience．The new method can tune t
