A switched system approach to networked control systems with time-varying delays

The stabilization problem is studied for the networked control systems with time-varying delay that is smaller than one sampling period. State feedback controllers are considered and a new switched system model is proposed to describe the resulting closed-loop NCS as a discrete-time switched system. Criteria of exponential stability for the closed-loop NCS and design procedures for the stabilizing controllers are presented by using the average dwell time method. An illustrative example is given to show the effectiveness of the proposed method.
