Identifiability of linear dynamic networks through switching modules

Abstract Identifiability of linear dynamic networks typically depends on the presence and location external (excitation or disturbance) signals, in relation to topology parametrized network model set. For closed-loop identification, it is known that switching (non-parameterized) controllers can also provide excitation, thereby rendering set identifiable. In this paper, we derive verifiable conditions for identifiability non-switching modules modules. These generalize classical result identification towards identification. Furthermore, path-based a generic sense are developed graph
