ℋ2 filter design through multi-simplex modeling for discrete-time Markov jump linear systems with partly unknown transition probability matrix

چکیده
This paper addresses the problem of H∞ filter design for discrete-time Markov jump linear systems (MJLS) with transition probability matrix affected by uncertainties. The proposed methodology allows to take into account the different types of uncertainties usually adopted in MJLS in a systematic way. New conditions are given for H∞ filter design with partial, complete or null Markov mode availability. Due to the presence of slack variables in the synthesis conditions and to the use of homogeneous polynomial solutions of arbitrary degrees, less conservative linear matrix inequality relaxations can be obtained. Numerical experiments illustrate the better performance and efficiency of the proposed approach when compared to other strategies available in the literature.

H2 Filter Design through Multi-simplex Modeling for Discrete-time Markov Jump Linear Systems with Partly Unknown Transition Probability Matrix
This paper is concerned with the H2 robust filtering problem for discrete-time Markov jump linear systems (MJLS) with transition probability matrix affected by uncertainties. Differently from previous approaches in the literature, the proposed strategy presents a systematic way to handle, simultaneously, different types of uncertainties commonly appearing in the transition probability matrix of...
متن کاملStabilization Analysis and Synthesis of Discrete-Time Descriptor Markov Jump Systems with Partially Unknown Transition Probabilities
A sufficient condition for the open loop system to be regular, causal and stochastically stable is proposed for a class of discrete-time descriptor Markov jump systems with partly unknown transition probabilities. The proposed criteria are in the form of a set of strict linear matrix inequalities and convenient for numerical realization. The presented condition used the information of unknown t...

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 c...
متن کاملFault detection reduced-order filter design for discrete-time Markov jump system with deficient transition information
The paper addresses the fault detection (FD) problem for a class of discrete-time Markov jump linear systems (MJLSs) with deficient transition rates, which simultaneously considers the totally known, partly unknown, and uncertain transition rates. Then, in accordance with the linear matrix inequality (LMI) method and the convexification techniques, a sufficient condition for the existence of FD...
متن کاملRobust stability, ℋ2 analysis and stabilisation of discrete-time Markov jump linear systems with uncertain probability matrix
The stability and the problem of H2 guaranteed cost computation for discrete-time Markov jump linear systems (MJLS) are investigated, assuming that the transition probability matrix is not precisely known. It is generally difficult to estimate the exact transition matrix of the underlying Markov chain and the setting has an special interest for applications of MJLS. The exact matrix is assumed ...
