Abstract

Bu çalışmada, kesintisiz güç kaynağı (KGK) çıkış gücü düzenlemesi için geleneksel oransal-integral (PI) kontrolör, bulanık mantık (BM) ve kazanç çizelgesi uyarlanır (KÇU) tabanlı PI kontrolörlerin tasarımları ve performansları sunulmaktadır. KGK’larda evirici için kontrolör tasarımında yaygın olarak sabit katsayılı geleneksel PI kontrolör kullanılmaktadır. Ancak sabit katsayılı kontrolör yerine katsayıları güncellenen kontrolörler daha iyi performans sağlayabilirler. Bu nedenle, evirici çıkış gücü düzenlemesi için kontrolör katsayılarını güncelleyen, BM ve KÇU tabanlı PI kontrolör tasarımları gerçekleştirilmiştir. Benzetim ve deneysel çalışmalarda, 5𝑘𝑊 KGK sisteminin performans sonuçları sistem çıkış geriliminin toplam harmonik bozulma ve ortalama mutlak hata değerleri açısından karşılaştırılmıştır. Deneysel çalışma sonuçlarına göre, en iyi sonucu KÇU tabanlı PI kontrolör sağlamıştır.

Performance Comparison of Fuzzy Logic and Gain Scheduling Adaptive Based PI Controllers for Uninterruptible Power Supply Output Power Regulation

Abstract

In this study, the designs of the conventional proportional-integral (PI) controller, fuzzy logic (FL), and gain scheduling adaptive (GSA) based PI controllers and their performances are presented for uninterruptible power supply (UPS) output power regulation. The conventional PI controller having constant parameters is commonly used for the inverter in UPS. However, controllers whose parameters are updated instead of using fixed parameters one might provide better performance. Hence, FL and GSA based PI controller designs, which update the controller parameters for the inverter output power regulation, have been implemented. In simulation and experimental studies, the performance results of the 5𝑘𝑊 UPS system have been compared in terms of total harmonic distortion and mean absolute error values of the system output voltage. According to the obtained results of the experimental study, the best result was obtained by the GSA based PI controller.
