Modeling and stabilization for networked control systems with time-triggered asynchronous sampling and network induced delay

The modeling and stabilization for the networked control systems with numbers of subsystems, are investigated in this paper. In order to eliminate conflictions and reduce network induced delay, a time-triggered asynchronous sampling mechanism is introduced, and the feature of network induced delay is analyzed. Then a distributed control law which uses the newest sampling date for control purpose, is delivered. And the networked control system is modeled as a discrete time system with uncertainty. A stability criterion is presented based on a Lyapunov function and matrix inequalities. An iterative algorithm for controller design is presented. Finally, a numerical example is given to validate the approach.
