Application of temperature fuzzy self-tuning PID controller in a resistance furnace

Aiming at the complicated system of calcining the workpieces in the resistance furnace, This work presents the method of using fuzzy self-adaptive PID controller to improve controlling accuracy of the resistance furnace. It improves system response, makes function more steady and lowers the using of energy and original material. It also lowers waster rate, and calcined workpieces are good in function. The trial results indicate that the control system has the good application value.
