This paper studies the velocity-consensus problem of multi-agent systems with second-order agent dynamics and proposes an asynchronous distributed consensus protocol allowing for switching interaction topology, time-varying delays and intermittent information transmission. Unlike the existing works, the agreement of position-like states is not required in this paper. Velocity consensus is a prerequisite...
The paper studies asynchronous consensus problems of continuous-time multi-agent systems with discontinuous information transmission. The proposed consensus control strategy is implemented based on the state information of each agent's neighbors at some discrete times. The asynchrony means that each agent's update times, at which the agent adjusts its dynamics, are independent of others'. Furthermore,...
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...
In this paper, we study the consensus problems for networked dynamic systems with arbitrary initial states, and present some structural characterizations and direct construction of consensus functions. For the consensus problems under similar transformation, we establish some necessary and sufficient conditions by exploiting the structure of consensus functions. Finally, we discuss the consensus problems...
