Controller Design Based on Delay Random Distribution for Networked Control Systems

A class of nonlinear networked control systems with delay is studied in this work. On the basis of different random distribution characteristics of network induced delay's main two parts, sensor-controller delay and controller-actuator delay, an asymptotically stability criteria is derived for the close-loop system by Lyapunov-Krasovskii functional method. By introducing delay random distribution characteristics to close-loop system function, a novel Lyapunov-Krasovskii function that could lower the conservativeness of controller design method is developed. Simulation example shows the effectiveness of the proposed method.
