Motion Control for Raw Material Transportation Systems

Problems: Tracking control can be used to move AGVs around a factory to transport roll paper for printing. Using tracking control, however, means that the AGVs must be moved in order, and a large amount of time is lost waiting in line. With tracking control, the motion of the transportation vehicles is determined in advance and it is very difficult to make operation changes (e.g., interruptions). Write motion instructions (e.g., type, destination) to Data Carriers (ID Tags) mounted to the AGVs. Read the Data Carrier information at the stations and perform motion control of the AGVs as appropriate (e.g., instructions to move to material supply stations, standby stations, or production stations).
