This paper provides consensus analysis for networked continuous-time multi-agent systems via sampled control. The sampled control protocol is induced from a continuous-time consensus protocol by using periodic sampling technology and zero-order hold circuit. Meanwhile, time-varying delay that can be both smaller and larger than the sampling interval is taken into account. Based on graph theory and...
This paper presents a general delay swarm model to study the collective behavior of a group of autonomous agents in the presence of communication delays. It is proved that under certain conditions the swarm members will converge to a finite region around the swarm center and move together in a cohesive cluster following the motion of the center. For general cases, the delay swarm may display more...
In the study of consensus problems of continuous-time multiagent systems, continuous communication of state information among agents is rather a restrictive assumption. In this paper, we propose a discrete communication structure of multiagent systems, which allows for bounded time-varying communication delays, and derive a necessary and sufficient condition for the possession of consensus property...
In this paper, consensus problems for discrete-time multiagent systems with time-delays are considered. First, a necessary and sufficient condition for a system to solve a consensus problem is established by a new approach: pre-leaders-followers decomposition. Furthermore, by this method, consensus problems for systems with a single time-delay as well as with multiple time-delays are studied, and...
