## Abstract

Various control methods have been developed. Among of these, however, having poor result. To overcome the existing problems, Fuzzy Logic based PID Self-Tuning algorithm was proposed in this final project. This method is based on PID, actually, but then, the three parameters of PID, in these terms Kp. Ti, and Td are regulated by Fuzzy Logic. By using Ziegler-Nichols as the auto-tuning method, initial values of PID parameters should have derived. β, as the set point weighting factor will having influence in Kp, whereas α, will affect on integral and derivative terms. Both α and β are regulated by fuzzy logic, which error and rate of change of error are employed as fuzzy input. So that, the value of the three PID parameters will be varied during operation depend on the operating conditions. In this final project, three phase AC induction motor is used as a plant to be controlled. By using Atmega32 microcontroller, triggering driver, and three-phase inverter as the interface, so that by applying Fuzzy Logic based PID Self-Tuning as the method, the inverter triggering-frequency can be controlled by giving PWM among 0V to 5V. It is remained approaching or equalizing to set point by the controller, although there are load disturbances during operation. By employing Fuzzy Logic based PID Self-Tuning method, poor system response when approaching set point and load disturbance can be reduced. Keywords : Three-Phase AC Induction Motor, Three-Phase Inverter, PID Self-Tuning, Fuzzy Logic, Atmega32 Microcontroller.
