多机器人系统的约束驱动协调控制

Constraint-Driven Coordinated Control of Multi-Robot Systems

摘要:

在本文中,我们提出了一个重新制定-框架作为一个约束优化问题-多机器人的任务,通过编码的成本函数,是要最小化。这种方法的优点是多方面的。基于约束的公式提供了一种自然的方式,使长期的机器人自主应用,其中弹性和适应性不断变化的环境条件是必不可少的。此外,在一定的假设下的成本函数,所得到的控制器是分散的。此外,可以实现有限时间收敛,同时仅使用局部信息,因此保持了算法的分散性。已开发的控制框架进行了测试的一个团队的地面移动机器人实施长期的环境监测。

英文摘要:

In this paper we present a reformulation--framed as a constrained optimization problem--of multi-robot tasks which are encoded through a cost function that is to be minimized. The advantages of this approach are multiple. The constraint-based formulation provides a natural way of enabling long-term robot autonomy applications, where resilience and adaptability to changing environmental conditions are essential. Moreover, under certain assumptions on the cost function, the resulting controller is guaranteed to be decentralized. Furthermore, finite-time convergence can be achieved, while using local information only, and therefore preserving the decentralized nature of the algorithm. The developed control framework has been tested on a team of ground mobile robots implementing long-term environmental monitoring.
