Implementation and Design of Fuzzy Controller for high Performance Buck-Boost and FIyback Converters

Abstract

This paper considers comparison of dynamic performance of PI and fuzzy controllers for DC buck-boost and flyback converters. It is shown that fuzzy control is superior to classical PI control in terms of response time, stability and accuracy under different operating conditions. Moreover, it is underlined that fuzzy controller is more suitable to control buck-boost and flyback converters. Experimental results on dSPACE DS1104 board based test bench for buck-boost in tracking mode, demonstrates its flexibility, robustness and efficiency.
