Robust H-infinity output dynamic observer-based control design of uncertain neutral systems

摘要

In this paper, the robust H-infinity control problem of output dynamic observer-based control for a class of uncertain neutral systems is considered. The linear matrix inequality optimization approach is used to design the new H-infinity output dynamic controls. Three classes of H-infinity observer-based controls are proposed. The minimal H-infinity-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-infinity observer-based controls. A numerical example is given to stress the usefulness of the proposed results.
