摘要:

本文提出了一种解决多机器人系统在存在延迟通信通道中协调问题的方法。所提出的方法利用控制屏障函数,以确保多机器人系统保持阻尼性。这是通过将阻尼性保持条件编码为不变集约束来实现的。该约束随后被包含在优化问题中,其目标是通过最小侵入性的方式修改机器人名义输入。所提出的优化问题具有分布式特性,即为了解决该问题,不需要个体机器人访问全局信息。此外,由于其凸性,每个机器人可以使用快速高效的算法来解决该问题。所提出控制框架的有效性通过在具有延迟的移动机器人团队上实现编队控制算法来验证。

英文摘要:

In this paper, we present a solution to the problem of coordinating multiple robots across a communication channel that experiences delays. The proposed approach leverages control barrier functions in order to ensure that the multi-robot system remains dissipative. This is achieved by encoding the dissipativity-preserving condition as a set invariance constraint. This constraint is then included in an optimization problem, whose objective is that of modifying, in a minimally invasive fashion, the nominal input to the robots. The formulated optimization problem is decentralized in the sense that, in order to be solved, it does not require the individual robots to have access to global information. Moreover, thanks to its convexity, each robot can solve it using fast and efficient algorithms. The effectiveness of the proposed control framework is demonstrated through the implementation of a formation control algorithm in presence of delays on a team of mobile robots.
