A novel implementation of MPPT sliding mode controller for PV generation systems

This paper presents a simulation of PV system (PV panel, boost inverter and a resistance load) using M-file of 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. In this paper the understanding and the good modeling of any system allowed us to create an algorithm which is applied in any programming software in our case M-file of MATLAB, the use of M-file presents many advantages like a short time of simulation.
