摘要:

在本文中,我们提出了一种新的分布式编队控制方法,自主机器人遵循所需的形成,同时跟踪动态环境中的移动目标。在我们的方法中,所需的编队,其中包括虚拟节点排列成特定的形状,首先生成。然后,自主机器人的控制所提出的人工力场,以收敛到这些虚拟节点没有碰撞。基于李雅普诺夫方法的稳定性分析。此外,在避障控制器的设计中,一种新的旋转力场和排斥力场的组合允许机器人避开和逃离凸和非凸形状的障碍物。以V形编队和圆形编队为例,利用各自的优势,验证了该方法的有效性。

英文摘要:

In this paper, we propose a novel and distributed formation control method for autonomous robots to follow the desired formation while tracking a moving target in dynamic environments. In our approach, the desired formations, which include the virtual nodes arranged into specific shapes, are first generated. Then, autonomous robots are controlled by the proposed artificial force fields in order to converge to these virtual nodes without collisions. The stability analysis based on the Lyapunov approach is given. Moreover, a new combination of rotational force field and repulsive force field in designing an obstacle avoidance controller allows the robot to avoid and escape the convex and nonconvex obstacle shapes. The V-shape and circular shape formations with their advantages are utilized to test the effectiveness of the proposed method.
