Application of Fuzzy Logic Controller in Shunt Active Power Filter
نویسنده
چکیده
This paper presents application of fuzzy logic controller for shunt active power filter to improve power quality in the distribution systems. The main feature of fuzzy logic controller does not require any complex mathematical model of the systems to regulate dc bus capacitor voltage. The reference compensating current has been estimated by unit vector template generation technique. The actual compensating current of the active power filter tracks the reference current by conventional hysteresis band current control scheme. The performance of fuzzy logic controller has been compared with conventional PI controller. The transient response of proposed fuzzy controller is found to be better than conventional PI controller. The simulation study has been performed on MATLAB simulink.
