| Abstract: | The problem of state observer-based non-fragile H∞ robust control for a class of uncertain time-delay linear systems is studied. The uncertainties exist not only in the plat, but also in the gains of the observer and the controller. Using the Lyapunov theory and linear matrix inequality (LMI) method, criteria for the existence and design method of the non-fragile observers and robust controllers are derived. The practical applicability of the proposed method is illus... |
