Resilient asynchronous H

designed for discrete-time Markov
jump systems: Static output feedback
case

Abstract
This article is concerned with the problem of resilient asynchronous H
N
static output feedback control for discrete-time
Markov jump linear systems. By Finsler’s Lemma, and with the help of two sets of slack variables, the product terms of
system matrices and Lyapunov matrices are decoupled. Resilient asynchronous controller is designed to improve the
robustness of the controller and overcome the drawback that the controller cannot get the information of the system’s
mode. The controller that makes sure the closed-loop system is stochastically stable and with prescribed H
N
perfor-
mance is designed. The bilinear matrix inequalities are given as the sufficient conditions for the controller design, which
can be solved using linear matrix inequalities along with line search. This control strategy can be used in many practical
application fields, such as robot control, aircraft, and traffic control.

Introduction
In practice, because of the impact of external environ-
ment, internal failure, the communication delay such as
considered in Lu et al.,
1
the noise such as considered in
Lu et al.,
2
and other reasons, most of the subjects to be
described are dynamic and time-variant. Markov jump
linear systems (MJLSs)
3
are hybrid systems to describe
the dynamic subjects. Markov chain determines the dif-
ferent modes in the MJLSs. The values of the Markov
chain constitute a finite set. Due to the above-
mentioned characteristics, a lot of application

and
research

about MJLSs have been done in the past
few decades. In Zhang et al.,
4
MJLSs apply to model
the neural network systems. Economic systems are
described by MJLSs in Zhao and Zhang.

The control-
ler in form of observer based is designed for MJLSs in
Zhao and Zhang.

The problem of stability for MJLSs
is solved in Costa and Fragoso.
7
The observability and
detectability of MJSs is studied in Tan and Zhang.

In
Wu et al.,
9
the filtering problem for MJSs is considered.
The character of Markov not only used in the MJLSs
but also used in other process such as in Ma and Jia.

The operating principle of H
N
controller is that
designing a controller for the given system and making
sure the interconnection between system and controller
is internally stable. So, the H
N
norm can be used in the
