Abstract
This work is concerned with the decentralized control of traffic flow in highways using on-ramp metering and variable structure techniques. Both the estimation and the robust control problem are studied. Sliding mode observers are first proposed to estimate the state of neighboring highway segments in a two-highway-link model. Two independent variable structure controllers use the resulting estimates to locally stabilize the traffic flow around a desired set point, even if accurate estimation is not always possible.
