The main objective of the article is to develop techniques of robust control and their applications to communication and transportation networks. The following problems are studied in detail: (1) resource sharing: these systems belong to a class of hybrid systems where the plant to be controlled is a continuous drift free system, and the controller is implemented as a finite state machine; (2) admission control; ramp metering control problems can be studied in either distributed or lumped parameter setting. These two settings to an isolated case have been studied by the authors and solutions for these have been obtained; and (3) traffic routing. Traditionally both kinds of network systems have been treated using static optimization methods for congestion control. The traffic routing problem for both types of networks can be solved either in user-equilibrium setting or system-optimal. In user-equilibrium, the aim of the controller is to obtain equal travel times on alternate routes. In system-optimal setting, the aim is to obtain minimum total travel time on the entire network.
