A Mode-Independent H-infinity Filter Design for Discrete-Time Markovian Jump Linear Systems
نویسنده
چکیده
This paper addresses the problem of H∞ filtering for discrete-time linear systems with Markovian jumping parameters. The main contribution of the paper is to provide a linear matrix inequality approach for designing an asymptotically stable linear time-invariant H∞ filter for systems where the jumping parameter is not accessible. The cases where the transition probability matrix of the Markov chain is either exactly known, or unknown but belongs to a given polytope, are treated. The robustH∞ filtering problem where the system matrices for each operating mode are unknown but belongs to a given polytope is also considered. A new internal mean square stability condition as well as a bounded real lemma for discrete-time Markovian jump linear systems are also developed.

Reliable H-infinity Filtering for Discrete Time-Delay Markovian Jump Systems with Partly Unknown Transition Probabilities
In this paper, the reliable H∞ filtering problem is studied for a class of discrete nonlinear Markovian jump systems with sensor failures and time delays. The transition probabilities of the jumping process are assumed to be partly unknown. The failures of sensors are quantified by a variable taking values in a given interval. The time-varying delay is unknown with given lower and upper bounds....

This paper addresses the H2 and H∞ filtering design problems of discrete-time Markov jump linear systems. First, under the assumption that the Markov parameter is measured, the main contribution is on the LMI characterization of all filters such that the estimation error remains bounded by a given norm level, yielding the complete solution of the mode-dependent filtering design problem. Based o...
