Control and Experimental Analysis of DC-DC Boost Converter Based on Interval Type-2 Fuzzy Logic Controller

Öz

In this study, Interval Type-2 Fuzzy Logic Controller (IT2FLC) structure is proposed for the control of the output voltage of DC-DC boost converter. With this controller structure, it is aimed to improve the response of DC-DC boost converter structure against load changes. First, DC-DC boost converter structure has been experimentally developed for this purpose. Then two different experimental operating conditions are prepared to investigate the performance and reliability of the proposed controller. IT2FLC and Type-1 FLC (T1FLC) are compared under these conditions. dSPACE DS1104 controller card is used to apply these controller structures to experimental studies. According to the obtained results, it is clearly observed that the proposed controller structure is provided more satisfactory dynamic response than T1FLC in both experimental studies.

Aralıklı Tip-2 Bulanık Mantık Denetleyici Tabanlı Yükselten Tip DA-DA Çevirici Yapısının Denetimi ve Deneysel Analizi

Öz

Bu çalışmada, yükselten tip DA-DA çeviricinin çıkış geriliminin denetimi için Aralıklı Tip-2 Bulanık Mantık Denetleyici (AT2BMD) yapısı önerilmiştir. Bu denetleyici yapısı ile yük değişimine karşı DA-DA çeviricinin dinamik cevabının iyileştirilmesi amaçlanmıştır. Bu amaçla ilk olarak yükselten tip DA-DA çevirici yapısı deneysel olarak geliştirilmiştir. Daha sonra önerilen denetleyici yapısının performansının ve güvenilirliğinin incelenmesi için birbirinden farklı iki deneysel çalışma durumu oluşturulmuştur. AT2BMD ile Tip-1 BMD (T1BMD) bu çalışma durumları altında karşılaştırılmıştır. Bu denetleyici yapılarının deneysel çalışmalara uygulanabilmesi için dSPACE DS1104 denetleyici kartı kullanılmıştır. Elde edilen sonuçlara göre önerilen denetleyici yapısının her iki deneysel çalışmada da T1BMD’den daha tatmin edici dinamik cevaplar sağladığı açıkça gözlenmiştir.
