TThis study presents the modeling and simulation of a Buck-Boost converter designed for photovoltaic applications. The converter is controlled by a sliding mode control (SMC) technique, which has several advantages when utilized in DC-DC power converters. The design was simulated using MATLAB R2023a. To obtain more realistic results, the study used local solar irradiation during the summer months as the radiation incident on solar panels. The battery maintains voltage stability even during periods without solar irradiation. The results emphasized the advantages of the control method for producing a stable, long-lasting output voltage despite fluctuations in solar irradiation and uncertainty in system parameter values. Additionally, the control method reduces the tracking error to zero and speeds up the connection to the reference voltage. This work employs a second-order sliding-mode control strategy, specifically the super-twisting algorithm, to mitigate the chattering phenomenon commonly associated with first-order sliding mode. The effectiveness of the second-order sliding mode control (SOSMC) was confirmed by Fast Fourier Transform (FFT) analysis, which revealed a 75% reduction in total harmonic distortion (THD).
