LMI‐based passivation of LTI systems with application to marine structures by Nicolás Faedo, Yerai Peña‐Sanchez, Fabio Carapellese, Giuliana Mattiazzo, John V. Ringwood

“…Abstract Due to the inherent relevance of passive (physically representative) models for control, state‐estimation, and motion simulation in the field of marine systems, in this paper, an optimisation‐based approach to passivation of linear time‐invariant (LTI) systems is proposed with application to physically consistent dynamical modelling of marine structures. In particular, the presented strategy is based upon the introduction of a suitably designed perturbation, computed via minimisation of a linear objective subject to a specific set of linear matrix inequalities (LMIs). …”
