New Improved Hybrid MPPT Based on Backstepping-sliding Mode for PV System

Abstract

In this paper, new improved maximum power point tracking using combinedbackstepping - sliding mode has been designed and studied, it is very known that the sliding mode control provides a good performance, however the charting (oscillation) is the most drawback of this method. So, to overcome the previous dilemma, a novel combined MPPT employing backstepping and sliding mode controller has been proposed, modeling of PV system and proposed hybrid backstepping-sliding have been presented with details. Simulation tests have been carried out using BP SX 150 solar panel, obtained results demonstrate a huge improvement in term of tracking, less oscillation and low ripple.
