Abstract

A control for delivery system made up of a plurality of variable output feed sources each with an independently variable input of material defines the capability of each of the feed sources based on the level of material and combines these capabilities to define a total capability of the delivery system. An output setpoint for each source is determined based on its capability and a required setpoint is set based on a desired end product characteristic which is used to define a production rate based on total capacity, required setpoint and the production line characteristics. The process is iterative so that the production rate, e.g. speed of the line is varied iteratively depending on the then current capabilities of the feed sources of the system and the footprint of the feed sources are adjusted based on their sensed capabilities thereby to maximize production line speed based on capability.
