Stabilization of networked control system with time delay induced by network imperfections

Abstract

This paper deals with the problem of networked-control system stability. A networked control system with simultaneous consideration of flaws induced by networks is modeled as a time-delay system with input delay approach. The induced quantization error is considered as a sum of saturation and of a uniformly bounded disturbance. An approach based on time-delay model and time-dependent Lyapunov-Krasovskii functional is proposed to analyze stability and to design a controller.
