Design of Lower-Radiation and Constant Temperature Electric Carpet Based on Fuzzy Control PENG Xi-jun ，YANG Rui-feng Abstract：The hardware and its fuzzy control system of constant temperature electric carpet are introduced. To reject higher harmonic produced in process of temperature adjusting, a zero-crossing triggering technic is put forward. In fuzzy control system, the input signals are temperature error and its change rate, and heating power is output signal. Through fuzzy control algorithm, the purpose of automatic adjustment of temperature is achieved.
