| Abstract: | To investigates the problem of robust fauh detection for a class of uncertain large - scale system, the ,bjective is to minimize the difference between the residual and the weighted fault and to enhance the robustness to dynamic interconnected terms ,control inputs and model uncertainties, The existence condition of the filter is established by means of linear matrix linear matrix inequalities. The given example shows the application of the method. |
