Event-Triggered Prescribed-Time Observer-Based Globally Consensus Control for High-Order Multiagent Systems

This paper addresses the globally consensus control problem for nonlinear high-order multiagent systems (MASs) under a directed graph. A novel distributed event-triggered prescribed-time observer (EPTO) is first formulated for the followers, and it is able to accurately estimate the information of the leader agent in a prescribed-time interval. Additionally, the event-triggered condition is constructed for each distributed EPTO to avoid continuous transmission of the neighbor states. The prominent feature of this paper is the designed consensus control scheme, which ensures that the closed-loop system achieves globally prescribed-time stability under the control framework of the backstepping technology. The simulation example further verify the effectiveness of the EPTO-based consensus tracking control scheme.
