Kernel-based identification of nonlinear port-Hamiltonian systems
Brayan M. Shali, Henk J. van Waarde
Port-Hamiltonian systems provide a structured framework for modeling physical systems by explicitly capturing their energy storage, dissipation, and exchange. However, deriving suc…
Passive and reciprocal linear time-and-space-invariant systems
Brayan M. Shali, Rodolphe Sepulchre
Reciprocity is a fundamental symmetry property observed across many physical domains, including acoustics, elasticity, electromagnetics, and thermodynamics. In systems and control…
Linear time-and-space-invariant relaxation systems
Tihol Ivanov Donchev, Brayan M. Shali, Rodolphe Sepulchre
This paper generalizes the physical property of relaxation from linear time-invariant (LTI) to linear time-and-space-invariant (LTSI) systems. It is shown that the defining feature…
Towards a representer theorem for identification of passive systems
Brayan M. Shali, Henk J. van Waarde
A major problem in system identification is the incorporation of prior knowledge about the physical properties of the given system, such as stability, positivity and passivity. In…
