Event-triggered H∞ filtering for networked systems with fading channels

This paper is concerned with the event-triggered μ_∞ filtering problem for networked systems with fading channels. An event indicator variable is constructed and the corresponding event-triggered scheme is proposed, which is based on the relative error with respect to the measurement signal, to determine whether the measurement output is transmitted to the filter or not. The fading channels are described by modified stochastic Rice fading models. The purpose of the addressed problem is to design a set of time-varying filter such that the influence from the exogenous disturbances onto the filtering errors is attenuated at the given level quantified by a μ_∞-norm in the mean square sense. Simulation results demonstrate the effectiveness of the developed filter design scheme.
