| Abstract: | For a class of uncertain time-delay systems with uncertainties which do not satisfy matching conditions, the problem of robustness stability is studied based on the Lyapunov stable theory. By means of linear matrix inequality approach, a sufficient condition of the existence of the robustly stable controllers for the uncertain time-delay systems is put forward, and the design method of state feedback controllers is obtained such that the closed-loop uncertain systems are robustly stable. Finally, Simulations of a numerical example indicate the validity of the proposed methods. |
