A robust filtering for neutral delay system with polytopic uncertain

This paper concerns delay-dependent robust ℋ_∞ filtering for neutral delay systems with uncertainty, which is assumed to be of polytopic type. Based on the Lyapunov-Krasovskii functional, a new delay-dependent filtering criterion is proposed which ensure the error system be stability as well as ℋ_∞ -norm bound. The key features of the approach include the introduction of free-weighting matrices and model transformation. Numerical examples illustrate the effectiveness of the method and the improvement over some existing methods.
