Abstract:
1. A system for measuring and controlling one or more physical properties of a material flow during a manufacturing process, said system comprising: at least one measurement device adapted to capture measurements of a particular physical property of said material flow at predetermined intervals; a material adjusting device adapted to alter said particular physical property of said material flow in order to maintain said physical property at a target setpoint; at least one PID controller in communication with at least one PID control loop, said control loop utilizing at least a proportional portion and an integral portion thereof to detect deviations between setpoint physical property values and measured physical property values at points along said material flow and to automatically adjust said material adjusting device in response thereto; and optimization software for receiving compiled physical property measurement data collected from a period prior to, and subsequently of, one or more changes to an input of said controller, said optimization software adapted to use said compiled physical property measurement data to calculate optimized parameters for allowing said PID controller and said PID control loop to more quickly and accurately adjust said material adjusting device to eliminate said deviations.
