Dynamic Sliding Mode Control of DC-DC Converter to Extract the Maximum Power of Photovoltaic System Using Dual Sliding Observer

This paper concerns the maximum power extraction of a photovoltaic generator system (PGS). The PGS consists single (PV) cells. To improve efficiency PGS, it is necessary to work within its point (MPP). In output dependent on solar irradiance and operating temperature and, therefore, MPP would be varied. address this problem, converter should placed after smooth control signal used adjust duty cycle. other challenge total system, i.e., converter, uncertainty involved. overcome uncertainty, dynamic sliding mode (SMC) can regulate low-pass integrator before remove chattering in SMC. However, due integrator, states increase hence, we propose dual observer (DSO) estimate added state. For reliable comparison with conventional SMC, same proposed DSO applied both provided shows effectiveness SMC suppression real implementation respect
