Abstract :
In this paper, an intelligent control system using state-space feedback controller designed to track the maximum power radiation direction of the sun for a photovoltaic system in a varying direction environment will be studied. In fact, the study focuses on the ability of using the state space feedback controller to control the power oscillation around the optimal point such that the power dissipation is minimized. Furthermore, the control system based on the instantaneous power tracking and with respect to the nonlinear photovoltaic cell makes feasible to access the maximum possible electric power using tiny changes in the Single Ended Primary Inductor Converter (SEPIC).
