In this note, we discuss finite-time state consensus problems for multi-agent systems and present one framework for constructing effective distributed protocols, which are continuous state feedbacks. By employing the theory of finite-time stability, we investigate both the bidirectional interaction case and the unidirectional interaction case, and prove that if the sum of time intervals, in which...
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...
This paper considers a group of mobile autonomous agents moving in the space with a virtual leader. We investigate the dynamic properties of the group for the case where the topology of the neighboring relations between agents varies with time and the coupling matrix is asymmetric. We introduce a set of switching control laws that enable the group to generate the desired stable flocking motion. The...
This paper presents a real-time motion planning method for biomimetic robotic fish with kinematic constraints. Based on successfully developing a robotic fish prototype, we step further to study navigation problem of the robotic fish in dynamic water environments. Considering the inherent kinematic constraints of the robotic fish, a new control law is proposed to stabilize the robotic fish on a specified...
