This paper addresses the distributed H-2 and H-infinity control problems for multi-agent systems with linear or linearized dynamics. An undirected multigraph with loops is used to represent the communication topology of a multi-agent network. A distributed controller is designed, based on the relative states of neighboring agents and a subset of absolute states of the networked agents. The notions of H-infinity and H-2 performance regions are introduced and analyzed, respectively. A necessary and sufficient condition for the existence of a controller yielding an unbounded H-infinity performance region is derived. A multi-step procedure for suboptimal H-infinity controller synthesis is presented. It is also shown that the H-infinity performance limit of the network under the distributed controller is equal to the minimal H-infinity norm of a single agent achieved by using the state feedback controller. It is finally shown that, contrarily to the H-infinity case, the H-2 performance limit scales with the number of agents in the network. (C) 2011 Elsevier Ltd. All rights reserved.
