Determination of the target speed corresponding to the optimum functioning of a photovoltaic system pumping and regulation of the water level

Abstract

This paper deals with the problem of the water level regulation in the photovoltaic pumping system. To achieve this aim, a fuzzy logic controller has been developed in order to determine the reference speed needed for vector control of asynchronous motor taking into account the water level in the tank and the variation of solar irradiation. The mathematical model of the regulation of water level is built on the basis of Matlab-Simulink.
