Simulation of sliding mode controller to deliver maximum power from PV system using M-file

摘要

This paper presents a comparative study between P&O and sliding mode (SM) algorithm to track the maximum power of a PV panel using M-file of Matlab. To prove the efficiency of the proposed controller, these two MPPT in the global algorithm, one classical and the other one is intelligent. The different steps of these controllers design are presented together with their simulation. In one hand the use of M-file has been carried out to demonstrate the effectiveness of SM controller to draw much energy and to present a fast response against change in operation conditions. In the other hand the proper modeling of any system permits to create an algorithm which is applied in any programming software in our case M-file of MATLAB. We show that the use of M-file presents many advantages like a short time of simulation.
