1. Introduction
Recently, some eorts on ltering and control problem have
been put on the Markov jump linear systems with Markovian
jump time delays [1–7]. For example, [1] dealt with the robust
stabilizability and
∞
disturbance attenuation for a class
of uncertain descriptor time-delay systems with jumping
parameters. e transition of the jumping parameters in
the systems is governed by a nite state Markov process.
[2] addressed the problems of delay-dependent robust
∞
control and ltering for Markovian jump linear systems with
norm-bounded parameter uncertainties and time-varying
delays. e robust
∞
ltering problem for mode-dependent
time-delay discrete Markov jump singular systems with
parameter uncertainties is discussed in [3]. e energy-to-
peak ltering problem of Markov jump systems with interval
time-varying delay is investigated in [4]. e

fuzzy
control problem was considered for nonlinear stochastic
Markov jump systems with neutral time-delays in [5].
In practical applications, to research the nonlinear time-
delay system, the scholars considered the T-S fuzzy time-
delay model which is a kind of eective representation,
and many analysis and synthesis methods for T-S fuzzy
time-delay systems have been developed over the past years
[8–17]. So, many scholars extended this model to Markov
jumpsystemswithtimedelays[18–28]. Reference [18]was
concerned with an
∞
control for a class of T-S fuzzy
Markov jump system under unreliable communication links.
Reference [19] concerned with the adaptive synchronization
for T-S fuzzy neural networks with stochastic noises and
Markovian jumping parameters. Reference [20]wascon-
cerned with the stability and stabilization problems for a class
of nonlinear systems with Markovian jump parameters. e
T-S fuzzy model was employed to represent the Markovian
jump nonlinear systems with partly unknown transition
probabilities. Reference [21] dealt with the delay-dependent
asymptotic stability analysis problem for a class of fuzzy
bidirectional associative memory neural networks with time-
varying interval delays and Markovian jumping parameters
by T-S fuzzy model. In [22], the asymptotic stability of
fuzzy Markovian jumping genetic regulatory networks with
time-varying delays by delay decomposition approach was
investigated.
For singular systems, since the regularity, causality, and
stability are needed to be considered, this class of systems is
more complicated and dicult compared with standard state
