Strong structural controllability of linear systems revisited
Jan Christian Jarczyk, Ferdinand Svaricek, Benedikt Alt · 2011
Recently, the concept of strong structural controllability has attracted renewed attention. In this context the existing literature to strong structural controllability has been revisited and some of the previous results have been found to be incorrect. Therefore, in this paper an overview of the previous results on strong structural controllability, counter-examples and a new graph-theoretic characterization of strong structural controllability are given.
