A kind of control system for constant-temperature oven is designed in this paper using fuzzy intensity-transferring algo-rithm. First, a hardware system is designed for the temperature of oven with this main devices including AT89C51 MCU, Pt100, MOC3041 and BTA06. Then, the steps for control algorithm of intensity-transferring are listed in detail. Finally, the algorithm is programmed, hardware devices are connected, and the actual effect of the controller is observed on the module of LED circuit. The result of testing shows that the rise-time ...
