The proposed controller is based on passivity formulation since DC-DC Buck converter has a passive structure in open-loop. Additionally, the controller takes advantage of the PI actions to design a control law that guarantees asymptotically stability in the Lyapunov's sense under closed-loop operation. The proposed controller does not depend on the parameters, which makes it a robust controller. The robustness of the proposed controller is checked by comparing its dynamical performance in front of a conventional PID controller. All simulation results were fulfilled via MATLAB software. © 2019 IEEE.Recurso electrónicoapplication/pdfenghttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/conferenceObject10.1109/LASCAS.2019.8667557Asymptotically stability.DC-DC buck converterGlobal trackingPassivity-based proportional-integral controlControllersElectric invertersMATLABProportional control systemsThree term control systemsTwo term control systemsVoltage regulatorsAsymptotically stabilityClosed-loop operationDC-DC buck converterDynamical performanceGlobal trackingOutput voltage regulationPassive structuresProportional-integral controlDC-DC convertersinfo:eu-repo/semantics/restrictedAccessAtribución-NoComercial 4.0 InternacionalUniversidad Tecnológica de BolívarRepositorio UTB5719149364856919564100364492235003710497630057190661793
