This paper deals with the leader-following consensus problem for a class of second-order multi-agent systems with unknown Lipschitz nonlinear dynamics. Moreover, the control coefficients are assumed to be identical and bounded but unknown. The Nussbaum gain function technique is employed to deal with unknown the control coefficients. It is proved that the states of the multi-agent systems can achieve...
The leader-following consensus problem is investigated for second-order time-varying nonlinear multiagent systems with unmodeled dynamics and unknown parameters over directed communication topology. Under the assumption that the unknown nonlinearities satisfy Lipschitz conditions with time-varying gains, a local adaptive law is introduced for the design of consensus protocol that enable all followers’...
The guaranteed performance of the consensus control for general linear multi-agent systems with Lipschitz nonlinear dynamics and directed interaction topologies is investigated, where the directed interaction topology contains a spanning tree. By a special matrix transformation, the guaranteed performance consensus problems are transferred into guaranteed performance stabilization problems. Then,...
In this paper, the fixed-time group tracking problem for multi-agent systems with unknown inherent nonlinear dynamics is studied. A distributed tracking control protocol is introduced to ensure that the follower agents in each subgroup can track their respective leaders in a prescribed time regardless of the initial conditions. Compared with the existing works on group (tracking) consensus, we do...
