摘要：
In this note, various parameter identifiability concepts for nonlinear systems with time-delay are defined, complete characterizations of these concepts as well as easily checkable criteria are provided. It is proved that geometric identifiability is equivalent to identifiability with known initial conditions, algebraic identifiability implies geometric identifiability. As for identifiability with partially known initial conditions, an easy characterization is also provided.
