This paper is focused on the dynamic output feedback control of sampled-data system with actuator saturation using quantized measurements. The output signals are quantized before they are transmitted to dynamic output-feedback controller. An augmented system is constructed through a closed-loop system, which is a model with an interval time-varying delay and nonlinear items. Using discontinuous Lyapunov function and linear matrix inequality approach, the criterion of asymptotical stability is obtained; furthermore, on the basis of the above stability condition, we design a dynamic output-feedback controller. Lastly, the effective of the proposed method is proved by a numerical example.
