This paper investigates the delay-dependent L2 - L filtering problem for time-delayed switched Hopfield neural networks. A new type of L2 - L filter is proposed such that the filtering error system is asymptotically stable with guaranteed L2 - L performance. The criterion is formulated in terms of linear matrix inequalities (LMIs), which can be checked readily by using certain types of standard numerical packages. A numerical example illustrates the effectiveness of the proposed L2 - L filter. ICIC International
