چکیده :
Increasing global warming due to using fossil fuels and non-renewable energy for power generation has become one of the most critical problems of this century. Solar cells are one of the most promising alternative energy sources, but their efficiency is limited due to different environmental conditions. For improving efficiency, the maximum power point tracking (MPPT) method is used to extract the maximum power from the photovoltaic (PV) system. To achieve the maximum power point of the solar cell, a novel ant colony optimization-based fractional-order back-stepping sliding mode controller (FOBSMC) is proposed in this study. The proposed controller uses the P&O technique to control the PV voltage to achieve the maximum power point of PV systems. Finally, the performance of the proposed method is compared with that of a conventional back-stepping sliding mode controller.
