  This paper studies global and semi-global regulated state synchronization of
homogeneous networks of non-introspective agents in presence of input
saturation based on additional information exchange where the reference
trajectory is given by a so-called exosystem which is assumed to be globally
reachable. Our protocol design methodology does not need any knowledge of the
directed network topology and the spectrum of the associated Laplacian matrix.
Moreover, the proposed protocol is scalable and achieves synchronization for
any arbitrary number of agents.
