Robust H∞ control with exponent stability for time-delay uncertain systems

This paper is concerned with the robust H
∞
control with exponent stability for a class of time-delay uncertain systems Attention is focused on the design of controllers such that the resulting closed-loop system not only is exponentially stable but also satisfies, H
∞
disturbance disturbance attenuance via memoryless state feedback control. Sufficient conditions for feasibility are obtained in terms of LMIs. Moreover, optimization of LMI is considered such that the controller with low gain parameters is formulated.
