Robust Analysis and Control over Uncertain Networked Control System with Random Time Delays

This paper considered the robust stability problem of networked flight control system, which is a new research field with the widespread applications of avionics networks for the connection of onboard devices of the aircraft. Sufficient conditions for robust stability and stabilization of networked flight control system with random time delays and structured uncertainties are derived based on the Lyapunov-Krasovskii function approach. The memoryless state feedback control law is obtained by the solution of linear matrix inequalities (LMIs) that guarantees the robust stabilization of the uncertain discrete time-delay system. Numerical examples are given to illustrate the effectiveness of design procedure.
