Abstract
This paper addresses the problem of robust H∞ filtering design for uncertain Markov jump systems (MJSs) with mode-dependent quantized output and partly unknown transition probabilities. The data transmission and exchange are completed over a digital communication channel such that the system outputs need to be quantized before transmission. Attention is mainly concentrated on tackling the parameter uncertainty, unknown transition probabilities and output quantization. The parameter uncer-
M
tainty considered in this paper is assumed to be norm-bounded, and the exact information of transition probabilities matrix is partly unavailable. The quantization error of the output is transformed into a
ED
bounded nonlinearity via a model transformation. A mode-dependent filter is designed to ensure that the filtering error system is stochastically stable and has an H∞ noise attenuation performance index. Finally, simulation results are provided to illustrate the validity of the proposed results.

I. I NTRODUCTION Markov jump systems (MJSs), recognized as a special type of Markov switching systems [1]–[7], have been extensively investigated during the past decades. Many remarkable theoretical results on the stability analysis, stabilization, and filtering problems for MJSs have been presented [8]–[17]. To mention a few, the stabilization problem for a type of stochastic MJSs was established in [9]. The problem of
CR IP T
Kalman filtering for a class of uncertain linear continuous-time MJSs was discussed in [15]. The system mode switching [18] is dominated via a Markov process, and in the jumping process, the mode switching is related to transition probabilities that determine the system behavior. The transition probabilities of MJSs are assumed to be known in previous work [19], [20]. However, the exact information of transition probabilities is difficult to achieve, especially in the network environment. Consequently, many studies on
AN US
MJSs with partly unknown transition probabilities were reported [21]–[24]. For instance, the H∞ filtering problem for a class of discrete-time Markov jump linear systems (MJLSs) with partly unknown transition probabilities was established in [23]. The authors investigated the problems for a class of continuous-time and discrete-time MJLSs subject to partly unknown transition probabilities in [22]. Networked control systems (NCSs) [25]–[34] have attracted considerable attention due to the merits of NCSs such as high reliability, low cost and simple installation. In NCSs, for filter design and feedback
M
control, output measurements are transmitted via a digital communication channel such that the system outputs must be quantized before transmission [35]–[42]. Recently, many theoretical results have been
ED
studied for NCSs with quantization [27], [28], [38], [43]–[49]. To mention a few, the problem of reset quantized state control for continuous-time linear system was studied in [28]. The problem of output
PT
feedback control for NCSs with limited communication capacity was established in [45]. Hence, the quantized system outputs will also appear in MJSs, which will give us some challenges to study the
CE
problem of filtering design for MJSs with quantized outputs. The system state is often unavailable in the control systems due to the restriction of the measured approach. Such an issue leads to many influential achievements on estimation and filtering design for

a series of MJSs published in [23], [50]–[54]. The mode-independent and mode-dependent filter design approaches have been established, which can be found in [19], [23], [55]. However, the robust H∞
filtering design problem of MJSs subject to parameter uncertainty, mode-dependent quantized output and partly unknown transition probabilities is still not studied, which motivates us for this study. In this paper, the H∞ filtering design problem is considered for uncertain MJSs with partly unknown transition probabilities and mode-dependent quantized output.

A mode-dependent full-order filter is constructed to ensure that the filtering error system is stochastically stable and has an H∞ performance index.

Remark 1: Note that the mode-dependent quantizer can be viewed as an extension of the static quantizer in [27], [28], [60], [61]. When S = {1} , the mode-dependent quantizer (14) becomes the traditional static
quantizer in [27], [28], [60], [61]. The mode-dependent quantizer in (14) is more useful for MJSs since the parameters ρ(i,j) are related to the structure of logarithmic quantizer. Then, the influence of the mode

jumping in the control plant (3) will be regulated by each subquantizer qi (yj (t)). In the following part, a model variation is provided to describe the output quantization qi (y (t)) as memoryless bounded nonlinearities. We define the matrices as: h i ∆i , diag δ (i,1) , δ (i,2) , · · · , δ (i,p) , It is not difficult to find 0 < ∆i < Ip .

We can denote the logarithmic quantizer in (14) as the following scalar sector condition: (i,j) 1 − δ (i,j) yj2 (t) ≤ qj (yj (t)) · yj (t) ≤ 1 + δ (i,j) yj2 (t) , t ≥ 0, j = 1, 2, · · · , p.
The inequality (16) is equivalent to
(15)
(16)
[qi (y (t)) − (Ip − ∆i ) y (t)]T [qi (y (t)) − (Ip + ∆i ) y (t)] ≤ 0.
M
To design a filter for (3), we decompose the quantization function qi (·) into the following form: qi (y (t)) = (Ip − ∆i ) y (t) + qis (y (t)) ,
(17)

where qis (y (t)) : Rp → Rp . It should be pointed out that the transformed nonlinearity qis (y (t)) belongs

to the following set φs : n o φs , qis (y (t)) : Rp → Rp : qis (0) = 0, (qis (y (t)))T [qis (y (t)) − 2∆i y (t)] ≤ 0, y (t) ∈ Rp .

For simplicity, we define some matrices parameters as

W1i , Ip − ∆i ,
W2i , Ip + ∆i ,

Thus, (18) can be rewritten as n o φs , qis (y (t)) : Rp → Rp : qis (0) = 0, (qis (y (t)))T [qis (y (t)) − Wi y (t)] ≤ 0, y (t) ∈ Rp . Substituting (17) into (3) yields x˙ (t) = (Ai + 4Ai (t)) x (t) + (Bi + 4Bi (t)) w (t) , y (t) = C x (t) + D w (t) , i

Remark 2: As we know, the filtering error dynamics can be easily deduced according to the measured output y (t) in the conventional design of filtering. However, in this paper, it makes system (3) extremely complex to achieve the error dynamics in the existence of output quantization signal yq (t) . We decompose the quantization function qi (y (t)) into the form (17) to tackle the above difficulty.

VII. C ONCLUSION
The H∞ filtering problem has been investigated for MJSs with parameter uncertainty, partly unknown
ED
transition probabilities and mode-dependent quantized output measurement. Compared with the MJSs with completely known transition probabilities, the MJSs considered in this paper are more general. By
PT
Lyapunov-like theory, the sufficient conditions of desired full-order filter are derived to guarantee the stochastic stability of the resulting filtering error system with H∞ performance index. The validity of the
CE
proposed theoretical results has been illustrated via two examples. Future work will pay attention to use fuzzy control approach [62]–[65] or adaptive control approach [66]–[70] to handle MJSs with nonlinear
AC
plant and mode-dependent quantization. R EFERENCES
