Positive Realization of Stable Fractional Discrete‐Time Linear Systems
Łukasz Sajewski · Asian Journal of Control · 2013
Abstract The positive stable realization problem of fractional discrete‐time linear systems is formulated and a method for finding a positive stable realization of a given proper transfer matrix is proposed. Sufficient conditions for the existence of a positive stable realization of this class of linear systems are established. A procedure for computation of a positive stable realization is proposed and illustrated by a numerical example.
