Summary In this article, the analysis and design problems of H∞ filtering for a class of discrete‐time switched singular systems with time‐varying delay under an arbitrary switching signal are investigated. The main attention is focused on the design of a linear mode‐dependent filter guaranteeing the regularity, causality, and asymptotic stability of the resulting filtering error system with a prescribed H∞ performance bound. By using a multiple Lyapunov‐Krasovskii functional, and utilizing the linearization technique, novel sufficient conditions for the solvability of H∞ problem are derived in terms of linear matrix inequalities. Solving that, the desired filter gains can be determined. Any model transformation of system, which often leads the large computational burden is involved. The free weighting matrix technique is introduced to provide additional degree of freedom, which improves the conservativeness of the developed method. Finally, numerical examples are given to demonstrate the effectiveness and the merit of the proposed approach and to compare the obtained results with some previous works in the literature.

A fundamental, omnipresent feature of the global information age is that cyber-capabilities, e.g. computing, communication and control, are inherently embedded in numerous physical/engineered systems from the nano-world to largescale systems-of-systems. Many scientific/technological challenges require intensive multidisciplinary studies, calling for new formulations, techniques and innovative solutions from a spectrum of communities in systems engineering/control/communications. IJSCC offers a vibrant discussion forum in this interdisciplinary area, especially communication systems augmented by control techniques and control systems whose components are interconnected via communication networks. Contents: IJSCC publishes original papers, review papers, technical reports, book reviews, notes and commentaries. Special Issues devoted to important and timely topics in integrated control and communication systems will occasionally be published.
