Feedback Control Design for the Distributed Model for Mixed Sensitivity

This chapter presents the feedback control design of an isolated ramp metering problem where we use the distributed model of the ramp system with the control designed not only to keep the flow on the highway at a critical value but also to keep the queue length on the ramp small. We show the stability properties of the closed-loop system that is obtained by the application of the feedback control law on the ramp system. We verify the effectiveness of the feedback control law by running some simulation experiments using the designed feedback control law on the isolated ramp system.
