Reachability Indices of Positive Linear Systems
Rafael Bru, Carmen Coll, Sergio Romero, and Elena Sanchez
It is well known that positive linear systems have
differences in the concepts and characterizations of the
structural properties of reachability and controllability.
In this paper, the reachability indices of a positive
system are defined and consequently they are studied.
For that, a canonical form of the reachability indices is
given by positive similarity. From that canonical form,
it is established that the reachability indices are invariant
by positive similarity. At the end, a complete sequence of
invariants of a canonical reachability system is given.
