CONTROL LAW IMPLEMENTATION FOR SHORT HEADWAY VEHICLE-FOLLOWER AUTOMATED GUIDEWAY TRANSIT (AGT) SYSTEMS
Automated guideway transit (AGT) systems are a new class of urban transport in which automatically controlled vehicles operate on dedicated guideway networks. This report examines the implementation of a vehicle-follower control law for short headway AGT systems in terms of required sensor accuracy, controller structure, and data transmission requirements. In this report controller configurations are recommended for headways of 0.5 and 3.0 s that require an 8 bit uplink word at intervals of 0.1 and 0.5 s, respectively. Accomplishments, recommendations, and areas for further study are also presented.
