Increase Efficiency of Photovoltaic Pumping System Based BLDC Motor Using Fuzzy Logic MPPT Control
Authors: , , ,
Abstract: The aim of this paper is presentation of an approach for modeling , control and optimization of a photovoltaic pumping system which contains a PV generator , DC-DC boost converter, MPPT controller, DC-AC inverter and a BLDC motor. We use an intelligent control method for searching the maximum power point (MPP). This method uses a fuzzy logic controller applied to a drive a DC–DC converter to an optimal operating point using PV panel’s measured variables. The PWM signals are generated by the interaction of the motor speed closed-loop system and the current hysteresis. The motor reference current is compared with the motor speed feedback signal. The considered model has been implemented in Matlab /simulink environment. The results show the effectiveness of the proposed method under variation irradiation ,in order to increase the performance of the water pumping system.
