Digital Fuzzy Logic And Dahlin Control Design For A Dc-dc Boost Converter
Authors : Tahri Ghrissi . Tahri Fatima . Tahri Ali .
Abstract
This article presents an innovative methodology for digital control rules applicable to a DC-DC boost converter (BC). The State-Space Averaged (SSA) approach was used to develop the converter mathematical model, a crucial step in the control design of this study. The voltage control mode (VCM) for the continuous conduction mode (CCM) was implemented with utmost care and precision. The two discrete fuzzy logic controllers (FLC) and Dahlin were meticulously and rigorously synthesized, ensuring the method's robustness. An analysis of the amplitude variations in input voltage and load is also conducted to compare these two digital controllers. The method's efficacy is not just claimed but thoroughly validated. The simulation results, acquired via the SimPowerSystems MATLAB, are presented and discussed, providing concrete evidence of the control method's effectiveness.
