Observer-Based Output Feedback Event-Triggered Control for Discrete-Time Synchronization

With the development of smart cities and wireless communication technology, the demand for wireless sensor devices is increasing, and low power consumption as an important indicator, there are more and more scholars conducting related research, and event-triggered control has more advantages than time-triggered control when handling energy resource constraints. In this paper, for distributed wireless sensor networks (WSNs) systems with external disturbances, we propose an observer-based distributed event triggered discrete-time control strategy. By designing an observer to achieve the rejection role for external disturbances and the estimation role for neighbouring nodes, and designing an event triggered function to reduce the number of steady-state triggers, and using broadcast communication between wireless devices, we achieve a better saving of communication resources. Finally, the effectiveness of the proposed observer-based distributed event triggering control strategy is illustrated on a group of linear topological networks.
