Abstract
A dispenser that dispenses fluid is controlled using a feedback control system. The control system uses a positional encoder to determine the precise position of a valve contained in an actuator in order to control the dispensing of the fluid. Various motion profiles may be used to control the position of the valve. The motion profiles of the valve enable controlled variation of the amount of fluid dispensed over time and enable several specific improvements to the dispensing of sealant in the manufacture of metal and composite cans.
