Balancing time-varying demand-supply in distribution networks: An internal model approach

The problem of load balancing in a distribution network under unknown time-varying demand and supply is studied. A set of distributed controllers which regulate the amount of flow through the edges is designed to guarantee convergence of the solution to the steady state solution. The results are then extended to a class of nonlinear systems and compared with existing results. Incremental passivity and internal model principle are the main analytical tools.
