The manifold of unitary and symmetric matrices: characterization, Riemannian optimization and application to BD-RIS design
Ignacio Santamaria, Carlos Beltrán, Eduard Jorswieck +2
This paper proposes and analyzes Riemannian optimization algorithms on the manifold of unitary and symmetric matrices, denoted , which naturally models the scattering…
Univariate amenable functions
Carlos Beltrán
The concepts of amenable and compatible functions have been introduced in a recent work, in order to state precise mathematical theorems that guarantee that a backward stable algor…
Points on with low logarithmic energy
Carlos Beltrán, Federico Carrasco, Damir Ferizović +1
We describe several randomized collections of rotation matrices and analyze their associated logarithmic energy. The best one (i.e. the one attaining the lowest expecte…
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…
