Abstract�� The electrical heating element is often used in center air adjusting system. It is installed in the end of air supply duct system and can improve the control precision of temperature by combining with other elements in center air adjusting system. The temperature control method of electrical heating was presented, which adopted predictive Fuzzy-PID control arithmetic and realized steadytemperature control. The smith predictor, Fuzzy controller and PID controller were integrated into the new control method. The predictive Fuzzy-PID controllingto temperature in center air adjusting system was simulated in MATLAB. Its results indicate that the control method, whose control precision reaches ±0.1��, can improve the temperature stability and reduce the energy consume. This control method could be used in other similar instance with electrical heating element.
