Observers for Systems with Discrete and Distributed Delays
Automatic Control Laboratory, University of Ghent Grotesteenweg Noord 2, B-9710 Gent-Zwipzaarde, Belgium
An observer theory for linear systems containing discrete and distributed delays in its state- and output equations is presented. In particular, existence criteria for observers with finite-dimensional error dynamics are derived. The stabilizability and eigenvalue assignability of the observation error dynamics are expressed in terms of the invariant zeros of a matrix function P(s), depending on the discrete delay parameters and the parameters of a Gram-Schmidt expansion of the distributed delay terms.
