Abstract

In order to solve the problem that resistance-heated furnace has the disadvantage of non-linearity, slow time-variant and large delay and so on, a temperature control system of the resistance-heated furnace has been designed according to the fuzzy-PI algorithm. Because this method has the merits of both PI and fuzzy control, the temperature control effect is improved to large extent. When the temperature error between given value and measured value is too large, the fuzzy control is adopted. When the error is too small, the PI control is used. The simulation test is performed by MATLAB, and the results indicate that this system has the advantages of small overshoot, short adjusting time and good robustness.
