The robust passive control for uncertain neutral systems with neutral and discrete lags is studied. A robust and passive state feedback controller is designed for the uncertain neutral delay systems with uncertainties. By using the linear matrix inequalities and Lyapunov functions, The time delay of the system and the bounded constraints of the uncertain parameter norm, the conditions for the system passive stability and the expected state feedback controller expressions are given. Finally, the numerical examples given illustrate the effectiveness of the design method .
