Abstract

Abstract: Considered are the stability problem of the uncertain linear networked control systems with transmission delays and packet dropout. The networked control system is transformed into an uncertain linear system with transmission delay. Then，the stability analysis of the timevarying system with delay and uncertain structures is given by using a new Lyapunov function with the lower delay bound， and the LMI conditions are derived related to the delay bound. Finally， numerical examples are given to illustrate the less conservation of this method.

Key words: linear networked control system, stability, structured uncertainty, timevarying delay
