Title: Topics on diffusively-coupled control: sampled information exchange and the dangers of cancel culture
Abstract: The diffusively-coupled architecture is a well-studied key ingredient of numerous coordination algorithms for multi-agent systems. This talk is devoted to two lesser studied aspects of it. In the first half the classical consensus protocol under sampled, possibly intermittent and asynchronous, information exchange between neighboring agents will be addressed. I will demonstrate that a small deviation from the conventional modus operandi could lead to substantial simplifications of the analysis and improved performance. In the second half the internal stability of diffusively-coupled schemes will be discussed. The analysis leads to somewhat surprising conclusions and a curious twist on the classical pole-zero cancellation theme.
