Considering the importance and difficulty of temperature control in extraction process of Chinese traditional medicine, the traditional temperature control system is improved through combining fuzzy control and PID control into fuzzy PID control system. For the self-tuning of PID parameters is realized through fuzzy inference, the multi-function reaction jug gets the expected temperature rapidly and accurately. Through the simulation with the fuzzy control toolbox of the Matlab, results indicate that the auto-tuning fuzzy PID controller has high control accuracy, small overshoot and good dynamic performance. Meanwhile, its performance is much better than the traditional temperature control system.
