Application of data-driven realizations to port-Hamiltonian flexible structures

摘要

In this contribution, the validity of reduced order data-driven approaches for port-Hamiltonian systems is assessed by direct comparison with models obtained from finite element discretization. In particular, we consider examples arising from the structural dynamics of beams. Port-Hamiltonian beam models can be readily discretized by using mixed finite elements. The resulting numerical models are used to generate the input-output data. The data-driven realization is then compared to the original numerical model in terms of its bode plot and energy trend.
