摘要：In this paper, an event-triggered decentralized dis-turbance rejection control scheme is designed to simultaneously stabilize states and attenuate disturbances for a class of uncertain interconnected systems. Extended state observer and equivalent-input-disturbance approach are adopted to form control strategy to accommodate matched and mismatched disturbance in a unified way. Second, combining the advantages of continuous event triggering mechanism and discrete event triggering mechanism, a novel hybrid sampling strategy is formulated. Specifically, the switch of sampling modes is determined by the estimations of state and disturbance. Then, sufficient conditions in LMI form are established for controller and observer co-design, where the triggering threshold is considered as a predefined parameter of the LMI. Finally, a simulation example is provided to verify the effectiveness of the proposed method. ? 2025 IEEE.
