What is it about?

This paper is concerned with the problem of finite-time asynchronous H∞ filtering for a class of discrete-time Markov jump systems. The communication links between the system and filter are assumed to be unreliable, which lead to the simultaneous occurrences of packet dropouts, time delays, sensor nonlinearity and nonsynchronous modes. The objective is to design a filter that ensures not only the mean-square stochastic finite-time bounded but also a prescribed level of H∞ performance for the underlying error system over a lossy network. With the help of the Lyapunov–Krasovskii approach and stochastic analysis theory, sufficient conditions are established for the existence of an admissible filter. By using a novel simple matrix decoupling approach, a desired asynchronous filter can be constructed. Finally, a numerical example is presented and a pulse-width-modulation-driven boost converter model is employed to demonstrate the effectiveness of the proposed approach.
