| 英文摘要 |
| This paper considers the H-infinity filtering problem of 2-D discrete linear systems with output measurement
dropouts. Firstly, data dropout is modeled by a stochastic Bernoulli sequence, and then the stochastic dynamic equation
of state estimation error is established. Secondly, the mean-square asymptotically stable and H-infinity performance of
2-D systems are defined. A sufficient condition is given in terms of linear matrix inequalities, which guarantees the error
system to be mean-square asymptotically stable and has H-infinity performance. The condition can also realize the design
of the filter matrix parameters. Then, the result is also extended to the 2-D systems with uncertain parameters. Finally, the
effectiveness of the theoretical result is validated by a numerical example. |
