The finite-time passive filtering for a class of nonlinear systems with uncertainties is considered。 The nonlinear parameters are assumed to satisfy Lipschitz conditions。 An optimal robust passive filter with respect to the finite-time interval is designed while the exogenous disturbances are unknown but norm bounded。 Based on passivity theory and finite-time stability theory， the sufficient condition for the existence of finite-time robust passive filter is given by constructing appropriate Lyapunov function。 And then， applying linear matrix inequalities techniques， the design method of the finite-time optimal passive filter is derived and can be obtained in the form of linear matrix inequalities。 Finally， simulation results illustrate the effectiveness of the developed approaches。
