DESCRIPTION:In response to increasing size and complexity of modern\ncontr
 ol systems\, large-scale interconnected systems attract\nthe interest of s
 ystems and control researchers since quite\nsome time. The hope is that an
 alysis and design problems\ncan be solved based on the subsystems and ther
 eby to obtain\nscalable solutions with decreased overall complexity while\
 nstill maintaining guarantees for the performance of the\noverall system. 
 Besides the individual subsystems\, the\nconstituent parts of interconnect
 ed systems are the\ninterconnection topology and the individual links used
  to\nrealize the interconnections. We thus have _three_\n_dimensions of co
 mplexity_ in interconnected systems: System\ncomplexity\, topological comp
 lexity and link complexity. It\nturns out that the three dimensions of com
 plexity cannot be\naddressed independently. Elevated complexity along one\
 ndimension usually yields constraints along the other\ndimensions. In this
  talk\, the tradeoff between system complexity\nand topological complexity
  in consensus and synchronization\nproblems is explored. The key tool will
  be a novel _internal_\n_model principle for synchronization\,_ recently d
 eveloped\nby our group.
