Passivity-based control (PBC) theory is used as a control technique since the dynamical model of the boost converter has an intrinsically port-Hamiltonian structure, where PBC theory is based upon, to design stable controllers via Lyapunov stability theory. To control the photovoltaic solar system, a current control mode is used, since photovoltaic cells are mathematically modelled as current sources, where the photo-current determined by the solar irradiance and the cell's temperature. Proportional and proportional-integral passivity-based controllers are developed to operate the boost converter under current control mode to extract the maximum power available in the PV array. Simulation results are conducted via MATLAB/ODE-package software. © 2018 IEEE.Recurso electrónicoapplication/pdfenghttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/conferenceObject10.1109/EPIM.2018.8756428Boost converterCurrent control modeLyapunov stabilityPassivity-based control theoryPphotovoltaic arraysControl theoryControllersDC-DC convertersElectric current controlElectric power transmission networksHamiltoniansMATLABPhotoelectrochemical cellsPhotovoltaic cellsPower controlSolar power generationTwo term control systemsBoost converterCurrent control modesLyapunov stabilityPassivity based controlPhotovoltaic arraysElectric power system controlinfo:eu-repo/semantics/restrictedAccessAtribución-NoComercial 4.0 InternacionalUniversidad Tecnológica de BolívarRepositorio UTB56919564100556090966005719149364836449223500
