The Sliding Mode based Particle Swarm Optimization (PSO) Maximum Power Point Tracking (MPPT) for Photovoltaic (PV) Systems implemented in MATLAB is a computational approach used to enhance the efficiency of PV systems. This method employs sliding mode control and PSO optimization techniques to continuously track the maximum power point of the PV array, ensuring optimal energy conversion. By utilizing MATLAB, researchers and engineers can develop and evaluate the performance of this MPPT algorithm in real-world conditions, assess its robustness to environmental changes, and optimize its parameters for different PV system configurations. This approach holds promise for improving the energy harvesting efficiency of PV systems and maximizing their output under varying solar conditions.
