“…With the development of network and communication technologies, etc., various new challenging theoretical issues arise in the analysis and synthesis of a networked system, which can be regarded as one special kind of large scale systems that have attracted extensive research interests since almost half a century ago [8], [12], [17], [18]. Some examples are efficient utilization of the structure information like sparsity etc., in reducing computational costs in distributed estimation and control, analysis for their stability, controllability, observability [2], [5], [6], [7], [17].…”
