This paper is concerned with the solution bounds for discrete-time networked control systems via delay-dependent Lyapunov-Krasovskii methods.Solution bounds are widely used for systems with input saturation caused byactuator saturation or by the quantizers with saturation.The time-delay approach has been introduced recently for the stabilization of continuous-time networked control systems under the Round-Robin protocol in \cite{KunSCL12} and under a weighted Try-Once-Discard protocol in \cite{KunCDC12}, respectively.Actuator saturation has not been taken into account in \cite{KunCDC12} and \cite{KunSCL12}.In the present paper, for the first time the time-delay approach is extended to the stability analysis of the discrete-time networked control systems under both scheduling protocols and actuators saturation. The communication delays are allowed tobe larger than the sampling intervals.A novel Lyapunov-based method is presented for finding the domain of attraction.Polytopic uncertainties in the system model can be easily included in our analysis. The efficiency of the time-delay approach is illustrated on the example of a cart-pendulum system.
