In this article, the problem of event-triggered H-infinity filtering for general discrete-time nonlinear stochastic systems is investigated. An event-triggered mechanism is introduced to reduce the communication burden by judging whether the measured data should be transmitted. First, two results about the event-triggered H-infinity filtering for general discrete nonlinear stochastic systems are presented. Second, when the linear discrete-time stochastic system is considered, the corresponding event-triggeredH(infinity)filtering can be designed via linear matrix equality approach. Finally, a numerical example and a practical example about the vehicle roll angle estimation are presented to verify the effectiveness of the proposed new design method.
