abstract
In this paper, the stochastic admissibility analysis problem is investigated for a class of singular Markov
jump delayed systems (SMJDSs). The purpose is to establish some conditions such that the SMJDSs are
stochastically admissible and strictly (X, Y, Z)-
μ
-dissipative. A mode-dependent Lyapunov functional and
some novel inequalities are proposed for the considered SMJDSs. Based on these, some new stochastic
admissibility conditions are established. In comparison with the existing results, the advantage of the
obtained conditions lies in the fact that they are not only less conservatism but also more general. Four
numerical examples borrowed from some existing papers are given to demonstrate the effectiveness and
the reduced conservatism of the presented method.

1. Introduction
Singular systems referred to as descriptor systems, generalized
state-space systems, implicit systems, differential-algebraic sys-
tems or semi-state systems, have attracted a lot of researchers in
the past years. A great many of essential results and notions in
control and systems theory based on regular systems have been
successfully extended to the field of singular systems. In compar-
ison with the regular systems, singular systems are more general
and complex. The reason is partly because they can better describe
physical systems than regular ones. In addition, not only asymp-
totic stability but also the system regularity and impulse free (for
continuous-time singular systems) and causality (for discrete-time
singular systems) have to be simultaneously taken into account.
Consequently, singular systems have received particular interests
in the literature, see, for instance [7,8,18,33,36] and the references
therein.
In addition, more and more attention has been paid to the
study of Markov jump systems (MJSs), which are described by a
series of linear systems with commutations produced by a finite-
state Markov chain during the last years. MJSs successfully apply to
model many practical systems, which encounter random abrupt
changes in their structures and parameters [3,5,17,34,35,37,38].
When the dynamics of practical systems modeled by singular
systems change abruptly, it is natural to describe them by using
singular Markov jump systems (SMJSs) [9,27].In[15], Ma and
Boukas studied the sliding mode control problem based on a
singular Markov jump system approach, where a sufficient con-
dition which guaranteed the existence of linear switching surface
and the stochastic stability of sliding mode dynamics was given. In
[19], Qi and Gao dealt with the state feedback controller design
problem for singular positive MJSs with partly known transition
rates. However, it is worth noting that time delays are ubiquitously
in various applications of control systems which are ignored in
these papers. Therefore, it is not surprising that many researchers
have been devoting themselves to the investigation of singular
Markov jump delayed systems (SMJDSs), see, for example
[4,10,13,24,29].
On another research front, since the concept of dissipative
systems was proposed in [28], many scholars have been attracted
to analyze and investigate the dissipative property [2,23]. Very
recently, some results on dissipativity analysis have been reported
in the literature. To mention just a few, in [22], the dissipativity
