Abstract :This paper presents the real-time household oven design application of the microcontroller-based fuzzy control system of temperature. Because of the complexity, nonlinearity, and dead time, temperature control of the oven is still delegated to many factors. In the computer-aided design process, the mathematical model of the system is derived with an open-loop response. The extracted model is used to obtain the conventional PI control parameters and adjust the PI type fuzzy rule base, which is mainly derived intuitively from the control engineering point of view. Using traditional PI parameters and Fuzzy logic PI rule base, real-time temperature control was realized with the PWM signal generated at the output of the PIC18F4520 microcontroller. The PWM signal produced at the output of the PIC18F4520 microcontroller is used to drive the power circuit designed using IGBT`s. Oven responses are obtained for both Fuzzy and PI control systems, in which the developed PI fuzzy control has better performance with less overshoot, less rising and settling time, and smaller steady-state error. A detailed description of designed control systems and experimental works with performance are given.
