A compararative study between sliding mode controller and P&O controller applied to MPPT

Abstract

This paper presents a simulation of PV system (PV panel, boost inverter and a resistance load) using MATLAB, To prove the efficiency of this system we applied two method of MPPT in the global algorithm, one classical and the other one is intelligent: the first one is called Perturbation and observation (P&O) used in stand-alone places or in simple installation and the later is based on sliding mode, this method is used when we need a large installation. The different steps of the design of these controllers are presented together with its simulation. The performance comparison between sliding mode controller and P&O controller has been carried out to demonstrate the effectiveness of sliding mode controller to draw much energy and a fast response against change in working conditions.
