A comparative study of Proportional Integral Derivative controller and Fuzzy Logic controller on DC/DC Buck-Boost Converter

This paper presents comparative performance between Fuzzy Logic controller (FLC) and Proportional Integral Derivative controller (PIDC) on DC/DC Buck-Boost Converter. The evaluation of the output has been carried out and compared by software simulation using Matlab/Simulink. The controllers performance are compared based on dynamic respond of the controllers in term of rise time, settling time, overshoot, peak time and voltage deviations. DC/DC Buck-Boost Converter in this study is operated in Buck (step-down) and Boost (step-up) modes.
