| Popis: | Cyber-physical empirical methods enable to address problems that classical empirical methods alone, or models alone, cannot address in a satisfactory way. In CPEMs, the substructures are interconnected through a control system that includes sensors and actuators, having their own dynamics. The present paper addresses how the fidelity of CPEMs, that is the degree to which they reproduce the behaviour of the real system under study, is affected by the presence of this control system. We describe an analysis method that enables the designer of a CPEM to (1) identify the artefacts (such as biases, noise, or delays) that play a significant role for the fidelity, (2) define bounds for the describing parameter of these artefacts ensuring high-fidelity of the CPEM, and (3) evaluate whether probabilistic robust fidelity is achieved. The proposed method is illustrated by considering a substructured slender structure subjected to dynamic loading. |
