Extended event-driven observer-based output control of networked control systems

This paper investigates the event-driven observer-based output control of networked control systems. By introducing a tuning parameter and a weighting matrix, an extended event-driven threshold is proposed. To obtain the controller and observer gains in a convex manner, a constructive strategy is employed to extract the controller matrix coupled with Lyapunov variables and system matrices. Based on these approaches, a sufficient condition for the closed-loop system to be the global uniform ultimate boundedness is ensured in terms of linear matrix inequalities. The validity of the proposed method is illustrated via a numerical example.
