In this note, the problem of dissipativity-based filtering of two-dimensional (2D) peri-
odic Roesser systems is investigated. A discrete-time periodic Roesser model extensively
used in practical systems is introduced to describe 2D periodic systems. Moreover, it is
assumed that the periods of the augmented system in horizontal and vertical directions
are the same, which can greatly simplify stability analyses. By resorting to the periodic
Lyapunov functional approach that depends on periodical property of the augmented sys-
tem, less conservative results for the existence of 2D periodic filter are presented to ensure
the asymptotic stability and 2D (Q

) − β-dissipativity. Particularly, the parameters
of 2D periodic filter are derived with convex optimization method. Simulation results are
provided to verify the effectiveness and merits of the theoretical findings. In addition, the
correlation between optimal dissipative performance indices and different Lyapunov func-
tions is revealed.

1. Introduction
The 2D process has received a lot of attention in the past decades due to its application in a wide range of domains such
as repetitive processes, gas absorption, and circuit analysis [3,27,28,32] . The motivation of early work of 2D systems stems
from its wide applications. The authors in [16] firstly proposed the model of 2D systems to describe the 2D process. After
that, more attention has been paid to consider the dynamic analysis problem of 2D systems. In recent years, some remark-
able theoretical results on the 2D systems have been reported in [8,10–13,24,27,29,31] . Specifically, Li and Wang [11] adopted
the fuzzy approach to investigate the H
∞
control problem of 2D nonlinear systems and the expansion of [11] to time-delay
case were discussed in [10,13,24] . The resilient H
2
and H
∞
filtering problem for 2D systems in the Roesser form has been
discussed in [31] . In terms of Markov jump systems (MJSs) [22,33,34] , there are few results to consider the synthesis prob-
lem by integrating the 2D systems and MJSs. Gao et al. [8] firstly designed a controller for 2D systems with Markovian
jump parameter. Since then, a growing body of literature about 2D MJSs has been emerged. A design method of full-order
filter has been proposed for 2D MJSs in [27] . The generalized H
2
fault detection problem for 2D MJSs with partly unknown
transition probabilities has been addressed in [29] .
