Nonlinear Lyapunov Control of a Photovoltaic Water Pumping System

In this study, we present an alternative maximum power point tracking technique used in a solar water pumping system to produce the for modifying amount of pumped water. This was actually created primarily regulate duty ratio buck converter. order control array operating track point, nonlinear approach based on input–output feedback linearizing and Lyapunov stability theory is used. By adjusting irradiation level, introduced controller-containing photovoltaic generator direct current (DC) motor pump put test. Our method modeled Matlab-Simulink, simulation results were show that it significantly outperformed directly connected generator-energized pumps operational terms extraction performance under various sunlight conditions.
