Takagi-Sugeno fuzzy model for DC-DC converters

In this paper the analysis, design and simulation of a Takagi-Sugeno model for DC-DC converters, the buck-boost as a particular case study, are presented in order to analyze their performance compared to classical models of this converter. The model used for the Takagi-Sugeno fuzzy representation is the reduced nonlinear model. the Takagi-Sugeno fuzzy model is defined by eight rules and three parameters: input voltage (V
_cc
), capacitor voltage (v
_C
) and inductor current (i
_L
) in order to define the sector. The obtained results for the Takagi-Sugeno model simulation are compared to the obtained from the linear, nonlinear and reduced models.
