Robust Control Based On Sliding Mode of the Shunt Active Filter to Compensate For the Disturbing Currents in the Electric Power (original) (raw)

The present publication articulates on the robust control strategy of the shunt active power filter (SAPF) originally based on the sliding mode. The new control strategy is tested to control the SAPF to compensate actively for the disturbing currents in the electric power under the presence of the voltage disturbances. The simulation results reveal a perfect compensation for the currents disturbances and the reactive power with a contribution to improve the robustness in stability and in speed of the SAPF. The efficiency of the proposed control strategy contribute to the improvement of the supply current spectrum and the phase displacement factor. Consequently, the control strategy proposed allows the SAPF to improve the energy quality. Keywords-Shunt active power filter; Robust control; Sliding mode; Digital simulation; Energy quality
