    Performance enhancing of 3-phase UPQC using feedback linearisation based DPC technique for power quality improvement
    (University of Oum El Bouaghi, 2021) Dahdouh, Adel; Mazouz, Lakhdar; Brahim, Elkhalil Youcefa
    This paper presents the compensation principle using feedback linearization based DPC control strategies of the unified power quality conditioner, which aims at the integration of series-active and shunt-active power filters. In order to improve the performances of UPQC, a control method based on a feedback linearization based DPC controller combined with space vector modulation (SVM) is proposed. The purposes are to deliver compensation signals more quickly and accurately at varied load conditions and to eliminate voltage as well as current harmonics with good dynamic response. Extensive simulation results obtained by Matlab/Simulink for a passive load connected through an uncontrolled bridge rectifier validate the performance of the suggested control scheme. The comparison of these results with those obtained with a PI controller demonstrates the superiority of the proposed controller.
