A Kalman Decomposition for Possibly Controllable Uncertain Linear Systems
This paper considers the structure of uncertain linear systems building on
concepts of robust unobservability and possible controllability which were
introduced in previous papers. The paper presents a new geometric
characterization of the possibly controllable states. When combined with
previous geometric results on robust unobservability, the results of this paper
lead to a general Kalman type decomposition for uncertain linear systems which
can be applied to the problem of obtaining reduced order uncertain system
models.Comment: To appear in Automatic
