l1 Distributed Networked Controller Design for Networked Systems

This paper considers the problem of finding the l(1) optimal networked controller for a networked system, where both plant and controller are interconnected systems interacting over a directed causal network. Adopting Youla parametrization, the optimal l(1) control problem is formulated. Results show that distributed input to output l(1) optimal control problem is a convex problem under certain conditions, provide a controller that is realizable on the given network and a network realization.
