Leader-following consensus of second-order nonlinear multi-agent systems with unmodeled dynamics

In this paper, the leader-following consensus is investigated for a class of second-order nonlinear multi-agent systems with unmodeled dynamics. A new distributed protocol, which contains a designed signal to dominate the effects of unmodeled dynamics, is presented to solve the consensus problem for multi-agent systems. The protocol is designed without using the information of Laplacian matrix and the Lipschitz constants. It is proven that the...
