IMPROVEMENT OF THE DISMC METHOD VIA ISMC TO PROVIDE A FASTER RESPONSE TIME AND MITIGATE CHATTERING PHENOMENON

The presence of a Maximum Power Point Tracking (MPPT) algorithm in a PV system is driving the process at a Maximum Power Point (MPP) is mandatory since the PV array feature is non-linear and variable with changing climatic conditions, as a result, the maximum power generated is obtained. In this paper, a new robust MPPT technique proposes using the notion of a double integral sliding mode controller (DISMC) for a standalone PV system. The goal of this super-slide algorithm is to design a new sliding surface that will help improve slow transient response and mitigate chattering phenomenon compared to integral ISMC. The study permits compare both algorithms to get the best algorithm in terms of time response and the chattering phenomenon, in addition to efficiency, stability, and robustness. The modeling of the stand-alone PV system and the simulations were carried out using Matlab/Simulink.

Automated summary

The presence of an MPPT algorithm is essential for driving a PV system to operate at its maximum power point. This paper introduces a robust MPPT technique using a double integral sliding mode controller to improve response time and reduce chattering phenomenon.
