Abstract :
The conventional PID control based on precise mathematical model is difficult to guarantee heating process requirements because the heat treatment furnace with large inertia and time delay of nonlinear and time-varying characteristics. Designed the heating furnace fuzzy control system based on PIC16F877 MCU with the functions of data acquisition, furnace temperature control and fault detection. The process control uses the algorithm of self-optimizing rules which is studied thoroughly,and the entire heating process has realized automatic intelligent control in this way. A furnace for the object was simulated with MATLAB, simulation results show that the control system of high precision, small overshoot, reliability, which has some promotional value for the control of industrial furnace.
