Robust Control for Enhancing Photovoltaic System Performance Under Real Climatic Conditions: A Case Study in the Middle Atlas of Morocco

This paper delves into the utilization of an optimal and robust Integral Sliding Mode Controller (ISMC) for maximizing the power output in a photovoltaic (PV) system. The research covers two distinct periods—summer and winter—encompassing diverse atmospheric conditions. The innovative ISMC controller, introduced as a unique approach, ensures system stability through the application of the Lyapunov function. Comparative simulations, utilizing real-world data from Ifrane City in the Middle Atlas of Morocco, are conducted against the conventional Sliding Mode Control (SMC), validating the robustness and efficacy of the proposed ISMC. The results demonstrate the ISMC's superior resilience to atmospheric variations, showcasing rapid transition responses and enhanced tracking performance in comparison to SMC controllers.
