Descriptor realizations of autoregressive representations
1 Department of Mathematics, Aristotle University of Thessaloniki, Thessaloniki 54006, Greece
In Pugh et al.(1998, Automatica, submitted), fundamental equivalence between AutoRegressive (AR) representations has been defined. Actually, two AR-representations are defined to be fundamentally equivalent in the case there exists a bijective polynomial differential map between their behaviours. In this paper, it is shown how to reduce an AR-representation to a fundamental equivalent realization in descriptor form.
Keywords: autoregressive representations; descriptor systems; equivalence; realization; full equivalence.
