    Abstract :

    A Unified Power Quality Controller(UPQC) using a Fuzzy Logic Controller(FLC) has been proposed .The obtained through FLC are good in terms of dynamic response because of the fact that FLC is based on linguistic variable set theory and does not require a mathematical model of the system .Moreover ,the tuning of the PI controller is not required in case of FLC .Simulation are carried out using MATLAB/Simulink to validate the theoretical findings.
