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.

This paper presents a design of PID controller for furnace temperature control system with disturbance. Currently, PID controller has been used to operate in electric furnace temperature control system because its structure is simpler compared to others. However, the issue of tuning and designing PID controller adaptively and efficiently is still open. This paper presents an improved PID controller efficiency from tuning by Nelder Mead method. The parameters of PID controller shall be obtained from the Nelder Mead optimization procedure. Errors between desired magnitude response and actual magnitude response are calculated by using the Integral of Absolute Error (IAE). The proposed Nelder Mead based PID design method is simpler, more efficient and effective than the existing traditional methods included Ziegler Nichols, Cohen-Coon and Direct Synthesis. Simulation result shows that the performance of PID controller using this proposed method is better than traditional methods and resistant to disturbance.
