In this paper, the designing procedures of fuzzy weight PID controller is illustrated, and the control of temperature by sub computer system with fuzzy weight PID regulator has been realized on the experimental resistance stove. First, the model of the experimental resistance stove is built by using MATLAB software, and the PID parameter is adjusted according to experience formula of Ziegler Nichols. Second, a fuzzy weight PID controller is designed applying the theory on which the parameter of PID controller is regulated by fuzzy weight controller. Finally, the control of temperature with fuzzy weight PID regulator has been realized on the experimental resistance stove by using PC PLC sub computer system. As a result, the quality of control is very excellent.
