Simulation of New Simple Fuzzy Logic Maximum Power Point Tracker for Photovoltaic Array

Abstract

A new simple fuzzy method used for tracking the maximum power point tracker (MPPT) for photovoltaic systems is proposed. The input parameters   and duty cycle D are used to generate the optimal MPPT under different operating conditions, The photovoltaic system simulated and constructed by photovoltaic arrays, a DC/DC boost converter, a fuzzy MPPT control and a resistive load, The Fuzzy control law designed and the results in a simulation platform will be presented and compare to Perturbation and observation (P&O) controller.

Keywords: Photovoltaic, fuzzy control, Perturbation and observation algorithm (P&O), maximum power point.
