MPPT voltage oriented loop based on integral sliding mode control applied to the boost converter

Abstract

in this paper, an integral sliding mode control method is proposed for maximum power point tracking MPPT voltage oriented loop. The aim is to obtain a better performance when applying it to stand alone. The proposed technique is studied and simulated by using Matlab/Simulink and simpower system packages. The obtained simulation results display significant enhancements by applying the proposed method compared to the conventional P&O and Voltage oriented loop based PI controller methods in term of accuracy and oscillations around MPP it. This could help with decreasing the power losses.
