Distributed Coordination Control of Networked Lagrangian Systems With Velocity and Input Constraints Over Event-Triggered Communication

Abstract

In this paper, the coordination control problem of networked Euler-Lagrange (E-L) systems with velocity and input constraints over event-triggered communication is considered. A novel distributed controller is proposed to achieve the control objective under reasonable initial conditions. Unlike existing methods, neither the proposed controller nor the event-triggered scheme relies on any global information of the communication graph. Also, Zeno behavior is proved to be non-existent. In addition, the constraints on the system velocity and input will not be violated. Finally, case studies and experiment results are provided to show the effectiveness of the proposed method.
