Robust H∞ Observer-Based Control of Uncertain Neutral Systems with Mixed Delays

In this paper, the robust In this paper, the robust H ∞ control problem of output dynamic observer-based control for a class of uncertain neutral systems with discrete and distributed time delays is considered. Linear matrix inequality (LMI) optimization approach is used to design the new H ∞ output dynamic controls. The minimal H ∞ -norm bound and the maximal perturbed bound are given. Based on the result of this paper, the constraint of matrix equality is not necessary for designing the H ∞ observer-based controls. Finally, a numerical example is given to illustrate the efficiency of the proposed approach.
