Delay-dependent L2-L∞ Filter for Singular Time-delay Systems

The problem of L2-L∞ filtering is discussed for singular time-delay systems. Attention is focused on the design of full-order filter that guarantees the delay-dependent exponential admissibility and a prescribed noise attenuation level in L2-L∞ sense for the filtering error dynamics. The desired filter can be constructed by solving certain linear matrix inequality (LMI). Numerical examples are given to show that the methods have less conservatism.
