Abstract—In this paper, a microcontroller-based fuzzy logic controller is introduced to stabilize at the desired temperature, while sudden changes in temperature can be severe. This approach is applied to one onboard microcontroller which is on small board and the control system is able to meet the required respond quickly. The significance of this work is because of using a microcontroller with a fuzzy PI controller as the supervisor, and evaluated through experiments. It is shown that the characteristics of the fuzzy logic, such as flexibility of the I/O selection and saturation of the outputs, provide favorable performance to the control system for temperature system.

Index Terms—fuzzy logic controller, proportional integral derivative (PID), pulse width modulation (PWM)
