Abstract
This paper presents an improved new control technique of the stability of the DC-DC buck converter supplied by a standalone photovoltaic system. The newly designed control based on passivity PBC can stabilize the control system by taking into account the stored energy. The system is modeled under the formalism of Euler Lagrange, to build a passive control law while guaranteeing satisfactory static and dynamic performances. Designed controllers of PBC, photovoltaic panel, and DC-DC buck converter will be simulated using MATLAB/Simulink toolbox and they will be validated by an experimental setup, which ensures the stability and the robustness of the control synthesis in different tests.
