This paper considers the stabilization problem for neutral time-delay systems with actuator saturation under a sampled-data controller. For the actuator saturation, the saturation nonlinearity is represented as the convex combination of the state feedback and the time-delay feedback. Compared with the literature, this paper not only utilizes the looped-functional approach to handle the sampling interval, but also constructs the augmented vector related to the time delay into the Lyapunov functional. By employing integral inequalites, this paper proposes the local stabilization criteria in terms of linear matrix inequalities (LMIs). Numerical example shows the validity of the proposed criteria in the view of the maximum allowable sampling intervals and the estimates of the domain of attraction.
