Implementation of MPPT Algorithm Using Simulink S-Function in MATLAB

This implementation demonstrates the Maximum Power Point Tracking (MPPT) algorithm using S-functions in MATLAB's Simulink environment, which runs successfully! The approach involves creating a simulation environment first, followed by coding the MPPT algorithm logic within the S-function framework. The S-function implementation enables real-time monitoring and adjustment of system output power through continuous sampling and duty cycle optimization. Key algorithmic components include perturbation and observation methods, where the S-function systematically varies operating parameters and observes power output responses to track the maximum power point. This MPPT implementation significantly enhances solar energy utilization efficiency by maintaining optimal operating conditions, thereby improving overall solar system performance and energy conversion rates. The code structure includes initialization routines, update methods for real-time parameter adjustment, and output calculation blocks that interact with Simulink's simulation engine.
