This paper is concerned with the robust H∞ filter problem for networked environments,which are subject to both transmission delay and packet dropouts randomly.By employing random series which have Bernoulli distributions taking value of 0 or 1,the data transmission model is obtained.Based on state augmentation and stochastic theory,the sufficient condition for robust stability with H∞ constraints is derived for the filtering error system.The robust filter is designed in terms of feasibility of one certain linear matrix inequality (LMI),which is formed by adopting matrix congruence transformations.A numerical example is given to show the effectiveness of the proposed filtering method.
