A guaranteed cost based memory event-triggered control of networked control systems with multiple disturbances via an interconnected disturbance observer approach

This article is dedicated to event-triggered anti-disturbance control of networked control systems via a guaranteed cost triggering scheme. A distribution interconnected observer structure is built to estimate these unknown matched disturbances. A novel event triggered condition is constructed in terms of real-time cost and averaged functions composed of observer states and the last successfully transmitted one. A composite control scheme is provided by an event-triggered observer-based state feedback controller and compensators for the matched disturbances. A sufficient condition in term of linear matrix inequality is supplied to ensure the asymptotic stability of the resultant closed-loop system. A simulation is carried out to demonstrate the effectiveness of the proposed triggering control strategy.
