This paper considers a global robust output consensus problem for multi-agent nonlinear systems by general directed output interactions. For heterogeneous and minimum-phase nonlinear agents transformable into an output-feedback form, it is shown that the problem is solvable by an internal model approach under certain mild conditions. A dynamic output-feedback protocol is developed by converting the...
In this paper, we study pattern preserving path following control of unicycle teams with communication delays. The pattern of the vehicle team is said to be preserved if the distance between it and the desired one remains in some given range. A virtual vehicle formation is introduced such that each virtual vehicle becomes the pursuit target for the corresponding real vehicle. First, an input-driven...
Motivated by the famous Vicsek's model, this paper addresses the problem of heading consensus for a multi-agent group by using asynchronous decentralized algorithms. Two algorithms, one for the leaderless case and one for the leader based case are proposed. The appealing feature of both algorithms is that neither a global coordinate system nor a common clock is required. It is proved that these algorithms...
In this technical note, under widely used joint connectivity assumptions, some necessary and/or sufficient conditions for the heading consensus of autonomous multi-agent systems described by Vicsek's model are proposed. Further, more general nonaveraging protocols are studied for which necessary and/or sufficient conditions for the consensus are also given.
In this paper, we consider finite-time tracking problems of a moving target by multiple mobile agents. The mobile agents with global sensing areas and limited actuation region are designed to track down a target with estimation error with the help of formation and coverage. In order to capture the target, its location and velocity are first estimated. With observer-based estimation and formation control,...
