In this paper, we study the group consensus for networked Euler-Lagrange systems under a general nonsymmetric directed graph. The relationships between the interactive agents in the same group are cooperation while the relationships between the interactive agents among different group can be either cooperation or competition. Two assumptions are presented to achieve group consensus, respectively,...
We study the consensus problems for double integrators in this paper. Different from the existing works, the position and the velocity interactions among the agents are modeled by different graphs. We consider two different velocity interactions, namely, the balanced graph and a general directed graph. We propose fully distributed consensus algorithms with absolute velocity damping when position topology...
Motivated by the fact that the relative velocity information is difficult to obtain accurately, in this paper, we propose a leaderless consensus algorithm with gain adaptation for multiple Lagrangian systems without using neighbors' velocity information. By introducing an integral term in the auxiliary variable design, the final consensus equilibrium can be explicitly derived. We show that this equilibrium...
In this paper, we study the leaderless consensus problem for multiple Lagrange systems in the presence of parametric uncertainties under a directed graph. By introducing an integrate term in the auxiliary variable design, the final consensus equilibrium can be explicitly derived. We show that this equilibrium is dependent on three factors, namely, the interactive topology, the initial positions of...
In this article, we propose a target detection method in wireless sensor networks based on distributed data fusion. Firstly, we introduce a tree topology. It is different from the conventional tree topology, the sensors in our topology are assigned with weights which are proportional to the received Signal to Noise Ratio (SNR), and are arranged orderly. So the Fusion Center (FC) achieves the highest...
In this paper we study the attitude coordinated tracking problem for formation spacecraft under a directed graph. We design a distributed coordinated tracking algorithm which guarantees all followers to track the leader. It is shown that the closed system is asymptotically stable as long as the directed communication topology characterizing the interaction among the followers and the leader contains...
