Abstract
Purpose ‐ Aims to formulate and solve the minimal positive realization problem for discrete-time linear single-input, single-output systems with many state time-delays. Design/methodology/approach ‐ A conceptual discussion and approach are taken. Findings ‐ Sufficient conditions for the existence of positive realizations of a given proper rational function are established. A procedure for computation of minimal positive realizations is presented and illustrated by an example. Originality/value ‐ Extends an earlier method for positive discrete-time systems with many state time-delays.
