AI总结:

研究具有切割平衡时变交互的连续时间共识寻求系统的收敛性,给出极限值相等的充分条件并证明其必要性,推广至离散时间系统。

摘要:

我们考虑连续时间共识寻求系统,其时间依赖的交互是切割平衡的,含义如下:如果一组智能体影响其余智能体,那么前者也受到后者至少成比例的影响。涉及对称互连的模型以及智能体值的加权平均守恒的模型是特例。我们证明此类系统总是收敛的。我们给出了关于演化交互拓扑的一个充分条件,使得两个智能体的极限值相同。反之,我们表明如果我们的条件不满足,则这些极限通常不同。这些结果允许处理智能体交互先验未知的系统,例如随机的或由智能体值内生决定的系统。我们还推导了离散时间系统的相应结果。

英文摘要:

We consider continuous-time consensus seeking systems whose time-dependent interactions are cut-balanced, in the following sense: if a group of agents influences the remaining ones, the former group is also influenced by the remaining ones by at least a proportional amount. Models involving symmetric interconnections and models in which a weighted average of the agent values is conserved are special cases. We prove that such systems always converge. We give a sufficient condition on the evolving interaction topology for the limit values of two agents to be the same. Conversely, we show that if our condition is not satisfied, then these limits are generically different. These results allow treating systems where the agent interactions are a priori unknown, e.g., random or determined endogenously by the agent values. We also derive corresponding results for discrete-time systems.
