Finite Frequency Robust H∞ Filtering for Uncertain Spatially Interconnected Time-delay Systems With Interconnected Chains

This paper deals with the problem of delay-dependent robust H ж filtering for uncertain spatially interconnected time-delay systems (SITSs) with interconnected chains in finite frequency domains. First, by the delay-dependent finite frequency bounded ream lemma (BRL) for uncertain SITSs with interconnected chains, a finite frequency robust H ж filter design method can be derived by solving a set of linear matrix inequalities (LMIs). Finally, a numerical example is provided to clearly demonstrate the effectiveness of the proposed method.
