Abstract :
In this paper, robust stabilization problems for Networked Control System (NCS) with data loss are investigated. We treat the data dropouts caused by network transmission data rate limit as a switch and obtain the discrete-time linear stochastic switch model for NCS. The stability analysis of closed-loop NCS with data dropout is studied, and a robust Hinfin state feedback controller is designed to deal with the disturbances and unexpected data loss due to uncertainty communication network. The stability analysis and controller design are based on LMI techniques.
