Goertzel Algorithm Based Shunt Active Power Filter Using Sliding Mode Controller
نویسندگان
چکیده
In this paper control of Goertzel Algorithm based shunt active power filter with sliding mode controller is considered. Shunt active power filter involves harmonics mitigation due to three phase non linear loads under balanced and unbalanced load conditions. The sliding mode controller is used to regulate voltage of the capacitor used in inverter. The sliding mode controller improves the dynamic response of the system and provides faster convergence. The performance of the sliding mode controller is compared with the conventional PI controller. The above system is investigated for balanced and unbalanced load conditions using MATLAB/Simulink. From the analysis it can be observed that the Goertzel algorithm based shunt active power filter with sliding mode controller gives a better response than the conventional PI controller. The simulation results prove the effectiveness of the proposed system. Keywords—Shunt active power filter, total harmonic distortion,Goertzel Algorithm, sliding mode controller.
