Stability and ℓ∞-gain analysis for discrete-time positive singular systems with unbounded time-varying delays

扫码查看
This study considers the stability and <inline-formula/>-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 <inline-formula/>-gain by exploiting the monotonicity of state trajectory. They show that the <inline-formula/>-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.
