Design of fuzzy logic controller for customized servo voltage stabilizer

In this work the design and implementation of FLC for customized servo voltage stabilizer for domestic and industrial application was proposed. Firmware for FLC for four operational modes is developed and embedded in ATmega 128 controller whereas the other work reports for fixed application. This servo voltage stabilizer uses single auto transformer and FLC controller works with closed loop feedback. The developed servo voltages stabilizer maintains good regulated output voltage for the unregulated input voltage from 150 V to 300 V.
