Abstract: This study considers the stability and ‐gain analysis problem for discrete‐time positive singular systems with unbounded time‐varying delays. By proposing some new techniques and employing mathematical induction method, the authors first derive a sufficient condition to analyse the stability of the system. The authors then investigate the ‐gain by exploiting the monotonicity of state trajectory. They show that the ‐gain for the considered systems is independent of the magnitude of delays and fully determined by the system matrices. The validity of the theoretical results is demonstrated by a numerical example.
