It’s a pleasure to announce the next PH seminar talk on Wednesday, January
14, 4 pm (CEST), with Karim Cherifi  (Besan?on university), on:

Title: System identification of port-Hamiltonian systems
Abstract:

System identification is essential in modeling, analysis, and control of
dynamical systems, particularly when first-principles models are incomplete
or unavailable. In this talk, we begin with a brief introduction to system
identification, outlining its main objectives, challenges. We then focus on
structured modeling frameworks, with particular emphasis on port-Hamiltonian
systems, which have attracted significant attention due to their strong ties
to physics, energy-based interpretation, and interesting properties for
control and stability analysis. We study system identification under explicit
structural and physical constraints, using the port-Hamiltonian formalism as
a unifying framework, starting with the identification of linear
port-Hamiltonian systems, and highlighting how structure-preserving
approaches can be leveraged to recover physically consistent models from
data. We then move to nonlinear port-Hamiltonian systems and discuss recent
methods that enable their learning from data, including generalizations to
higher-order and more complex systems through neural scaling laws. The talk
concludes with a discussion of current research directions, including
recently proposed architectures for learning port-Hamiltonian systems.
