A passivity-based control applied to a double cascade DC/DC converter using a fuel cell

In this paper, the supplied energy by a fuel cell is managed using a double boost converter. The study of the whole system begun by presenting the model of the fuel cell, followed by the system dynamics of the double boost converter described by the averaged 4th order nonlinear state space model, then a final model is derived using Euler-LaGrange (EL) system equations, based on such model, a robust non-linear controller is synthesized using the passivity-based control as a global defining and global stabilization control method. The simulation results have been performed through Matlab/SimPowerSystems environment and show that the designed controller meet its objectives.
