Coordination of Multiple Dynamic Agents with Asymmetric Interactions | | Long Wang

16 Feb 2005 | | Subject: | Statistics; Optimization and Control MSC-class: 93 | math.ST math.OC | | Abstract: | In this paper, we consider multiple mobile agents moving in Euclidean space with point mass dynamics. Using a coordination control scheme, we can make the group generate stable flocking motion. The control laws are a combination of attractive/repulsive and alignment forces, and the control law acting on each agent relies on the position information of all agents in the group and the velocity information of its neighbors. By using the control laws, all agent velocities become asymptotically the same, collisions can be avoided between all agents, and the final tight formation minimizes all agent global potentials. Moreover, we show that the velocity of the center of mass is invariant and is equal to the final common velocity. Furthermore, we study the motion of the group when the velocity damping is taken into account. We prove that the common velocity asymptotically approaches zero, and the final configuration minimizes the global potential of all agents. In this case, we can properly modify the control scheme to generate the same stable flocking. Finally, we provide some numerical simulations to further illustrate our results. | | Source: | arXiv, math.ST/0502341 | | Services: | Forum | Review | PDF | Favorites | |
