Abstract
Implementing a control system over a communication network induces inevitable time delays and packet dropout that degrade performance and can even cause instability. In this paper, adjustable deadbands are explored as a solution to reduce network traffic in networked control system and we presented a new modeling method for networked control system with random time delays and communication constraints based on quasi T-S fuzzy models. The stability for the kind of networked control system is analyzed based on robust stability theory and information scheduling. Parametric expression of controller is given based on feasible solution of linear matrix inequality (LMI).
