H∞ controller design for discrete-time Markovian jump systems with additive time-varying delays

This paper focuses on the H-infinity controller design problem for discrete-time Markovian jump systems with additive time-varying delays. By combining Lyapunov-Krasovskii functional approach and Wirtinger-based inequality, a sufficient condition is established such that the resulting closed-loop system is stochastically stable with a prescribed H-infinity performance level gamma. Then, by employing the singular value decomposition technique, the controller gains are given by using feasible solutions to a certain set of linear matrix inequalities. Finally, a numerical example is provided to illustrate the usefulness of the scheme developed in this paper.
