H∞ observer-based control for a class of uncertain neutral time-delay systems via LMI optimization approach

In this paper, the observer-based control for a class of uncertain neutral time-delay systems is considered. The linear matrix inequality (LMI) optimization approach is used to design the Hx, robust control with disturbance attenuation. Two classes of observer-based controls are proposed and their Hx-norm bounds are given. The control and observer gains are given from the LMI feasible solutions. A numerical example is given to illustrate the results.
