A continuous-time approach to networked control of nonlinear systems

Abstract

A nonlinear networked control system in which the system information is transmitted over the network through multiple communication channels is considered. Each channel is modeled by a time-varying delay element. Stability of the control system is studied using the Lyapunov-Krasovskii method for continuous-time delayed systems. The sufficient condition for stability of the networked control system is presented in the form of a compact LMI. The results are applied to a robot arm networked control system to show the capabilities of the proposed method for nonlinear networked control applications.
