Temperature Control System of Resistance Furnace Based on TMS320LF2407A

Abstract:

Aiming at the long time-delay and nonlinearity of resistance furnace temperature control, this paper analyzes the shortcomings of PID algorithm, and puts forward temperature fuzzy control system design methods of resistance furnace based on TMS320LF2407A DSP. Fuzzy control algorithm is applied to change the output duty cycle of pulse width modulation (PWM) wave, which achieves power adjustment control of resistance furnace temperature. Through field debugging, the results show that this temperature control system has fast speed of the dynamic response and high steady-state accuracy, and prove that fuzzy controller design method and PWM control measures are correct and effective.
