Robust non-fragile consensus for a class of leader-following multi-agent systems

This paper addresses the robust non-fragile leader-following consensus problem for multi-agent systems against state-dependent uncertainties and controller coefficient variations. Without the requirement of knowledge of uncertainties of agents and controllers, adaptive distributed controllers are constructed to guarantee the follower agents tracking the leader agent. Asymptotic consensus results of multi-agent systems can be obtained under the influence of uncertainties in agents and controllers based on Lyapunov stability theory. Finally, a multiple coupled aircrafts is used to verify the efficiency of the method.
