The proposed controller guarantees globally exponentially stability for the system under closed-loop conditions via proportional control design. An averaging model of the buck-boost DC-DC converter is employed to represent the dynamics of the system via port-Hamiltonian (pH) structure. Simulation results show that a unique control law can be used to the charging or discharging battery process. MATLAB/SIMULINK software is employed to validate the proposed control methodology. © 2018 IEEE.Recurso electrónicoapplication/pdfenghttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/conferenceObject10.1109/GreenTech.2018.00025Battery energy storage system (BESS)Bidirectional buck boost DC DC converterCharge/discharge battery operating modesCurrent control modeLyapunov stabilityPassivity based control (PBC)Charging (batteries)Control system stabilityElectric current controlElectric invertersEnergy storageHamiltoniansMATLABSecondary batteriesBattery energy storage system (BESS)Buck-boost DC-DC converterCurrent control modesLyapunov stabilityOperating modesPassivity based controlDC-DC convertersinfo:eu-repo/semantics/restrictedAccessAtribución-NoComercial 4.0 InternacionalUniversidad Tecnológica de BolívarRepositorio UTB57202648917562072502005720264716057198269531
