a-Robust Stability for Linear Time-delay systems with Linear Parameter Perturbations

A new robust state feedback controller design in the time domain is developedfor parametrically perturbed linear systems with time delay. The properties of the matrixnorm and measure are employed to investigate the a robust stability conditions of systemswith structured or unstructured perturbations.A methOd is proposed to design the robuststatc fcedback controller to satisfy the robustness requirement.Examples are given to illustrate the proposed method.
