Gain-Adaptive PID-fuzzy MPPT for PV System

Abstract

In this paper, in this paper, new improved maximum power point tracking based on Gain-Adaptive PID has been designed and studied using PID-fuzzy approach. PID controller is the most widely adopted method in industry due to many reason (simplicity, low cost), however, it’s not perfect suitable for systems, fuzzy logic is used to enhance PID controller by adapting the PID parameters. This paper present PID-fuzzy as maximum power point tracking (MPPT) for photovoltaic system to maximize photovoltaic outputs (voltage, power and current).
