Immersion of General Nonlinear Systems Into State-Affine Ones for the Design of Generalized Parameter Estimation-Based Observers: A Simple Algebraic Procedure

Romeo Ortega, Alexey Bobtsov, Jose Guadalupe Romero +1

Generalized parameter estimation-based observers have proven very successful to deal with systems described in state-affine form. In this paper, we enlarge the domain of applicabil…

Output Voltage Regulation of a Fuel Cell/Boost Converter System: A PI-PBC Approach

Rafael Cisneros, Romeo Ortega, Carlo A. Beltrán +2

In this paper we consider the problem of voltage regulation of a proton exchange membrane fuel cell connected to an uncertain load through a boost converter. We show that, in spite…
