Abstract :
This paper investigates the synchronization of a network of Euler-Lagrange systems with leader tracking. The Euler-Lagrange systems are heterogeneous and uncertain and contain bounded, exogenous disturbances. The network leader has a time-varying trajectory which is known to only a subset of the follower agents. A robust integral sign of the error-based decentralized control law is developed to yield semiglobal asymptotic agent synchronization and leader tracking.
