Adaptive fuzzy logic control of a DC-DC boost converter with large parametric and load uncertainties

In this manuscript, we propose an adaptive fuzzy logic controller for a DC-DC boost converter with parametric and load uncertainties. The control strategy aims to achieve accurate voltage tracking with unknown dynamics, highly parameter and load variations, and no current sensing. Therefore, robustness to uncertainties of large magnitudes is achieved without the inner current control loop, which reduces the number of sensors. Simulations demonstrate the tracking performance of the proposed control technique in the presence of different intensities of uncertainties.
