The IEEE Transactions on Control of Network Systems is committed to the timely publication of high-impact papers at the intersection of control systems and network science. In particular, the journal addresses research on decision and control systems characterized by a distributed or networked architecture, spanning modeling, analysis, estimation, design, and implementation, with an emphasis on analytical foundations. Topics covered by this journal include collaborative control, distributed learning, multi-agent systems, distributed optimization, control of collective behavior, distributed estimation, dynamical systems over graphs, coevolutionary networks, synchronization, large-scale complex systems, and control with communication constraints. Application areas relevant to control of network systems include smart infrastructure, multi-robot systems and swarm robotics, systems biology, smart health, computing, communications, transportation, manufacturing, power systems, sensor networks, social networks, and cyber-physical social systems.
