Temperature control of electric furnace based on fuzzy PID

To electric furnace´s characters as non-linear and time-varying, we designed a fuzzy PID controller, and made some simulation through MATLAB, at the same time we used a traditional PID controller and simulated, then compared the result of traditional PID controller with fuzzy PID controller´s result and analyzed the property. The result of simulation shows that the speediness, stability and anti-interference ability of fuzzy PID control are superior to those of traditional PID control.
