Structured systems are linear systems whose state-space matrices have a fixed pattern of zeros, and their other entries are free parameters. Controllability and observability of these systems have been studied since the 80's, and have been widely used in recent years for the study of network systems. Motivated by cyber-physical security, recent results characterize input-and-state observability, where both initial condition and an unknown input need to be reconstructed from the outputs. There are two kinds of results for structured systems: structural results characterize when a property is generically true (i.e., for almost all choices of the free parameters), while strongly structural results ensure that a property is true for all non-zero parameters. All characterizations involve properties of some graphs associated with the zero pattern.

Federica Garin is a researcher with the NeCS team at INRIA and GIPSA-lab, Grenoble (France). She received her B.S., M.S., and Ph.D. degrees in Applied Mathematics from Politecnico di Torino (Italy) in 2002, 2004, and 2008, respectively. She was a post-doctoral researcher at Università di Padova (Italy) in 2008 and 2009, and at INRIA in 2010. She is an Associate Editor in the IEEE-CSS Conference Editorial Board and in the European Control Association (EUCA) Conference Editorial Board. Her current research interests are in distributed algorithms and network systems.
