Synchronization of multi-agent systems with error constraints based on barrier Lyapunov function

Abstract： Synchronization of multi-agent systems with error constraints requires that the states of agents synchronize, meanwhile the synchronization error is required to be confined by a predefined bound. This paper proposes a distributed neuro-adaptive control for synchronization of the leader-follower multi-agent systems with error constraints, where both the leader and the followers are governed by unknown nonlinear dynamics. To solve the problem of synchronization error constraints, neural networks are employed to approximate the unknown nonlinearities of the system dynamics, and a novel distributed barrier Lyapunov function (DBLF) is developed to confine the synchronization errors. Then distributed neuro-adaptive control protocols are derived based on the Lyapunov stability analysis, in which the Lyapunov function is defined in terms of the proposed DBLF. A simulation example is finally provided to verify that the synchronization error constraints can be realized by employing the proposed control protocols.
