本文研究了多个网络节点效用函数的分布式约束一致性问题,考虑到局部约束可能会阻碍网络全局优化,这一问题本质上是具有挑战性的。针对这个问题,一个广义的框架是通过自我评估的方法,其中每个节点使用效用评估更新个人状态,只与邻居进行交互。在此框架下,推导了分布式约束一致性算法,并给出了收敛性和稳定性的理论分析。此外,为了便于工程实现,还提出了一种近似方法。最后,通过实例分析验证了算法的有效性.
This paper investigates the problem of distributed constrained consensus of utilities for multiple networked nodes, which is essentially challenging in view of the fact that local constraints may hinder the global optimization across the network. Focusing on this problem, a generalized framework is developed via a self evaluation approach, in which each node uses utility evaluations to update individual states by interacting with neighbors only. Following the framework, the distributed constrained consensus algorithms is derived, with theoretical analyses presented to show the convergence and stability. In addition, an approximation method is proposed as well for ease of engineering implementation. Finally, illustrative examples are provided and analyzed to substantiate the efficacy of the proposed algorithm.
