| Abstract: | This paper discusses the stabilization problem for a class of nonlinear discrete-time networked control systems.By modeling the sensor-to-controller delay and controller-to-actuator delay as Markov chains,the closed-loop systems can be expressed as jump nonlinear systems with two modes.By using the Lyapunov method and linear matrix inequality technique,the sufficient conditions on the existence of a stabilizing controller are constructed.Finally,effectiveness of our approach is illustrated by a numerical example. |
