Application of third-order sliding mode controller to improve the maximum power point for the photovoltaic system

In this research work, a third-order sliding mode control (TOSMC) is suggested to achieve the maximum power point (MPP) in a photovoltaic (PV) system application under variable weather conditions. Due to chattering phenomena, power losses increase when using the classical sliding mode control, and to reduce the steady-state error, ensure a good dynamic response, and achieve high power efficiency, a TOSMC strategy is applied to control the photovoltaic system. The studied system contains the PV panel, the DC-DC boost converter, the resistive load, and the proposed MPP tracking (MPPT) technique based on a TOSMC algorithm. This designed system is simulated using Matlab software, and the obtained simulation results show smaller steady-state error and good overall efficiency. (c) 2023 The Authors.
