A Fuzzy logic controller (FLC) based unified power quality controller is proposed. The results obtained through the FLC are good in terms of dynamic response because of the fact that the FLC is based on linguistic variable set theory and does not require a mathematical model of the system. Moreover, the tedious method of tuning the PI controller is not required in case of FLC. Simulations done using MATLAB/Simulink to validate the theoretical findings.
