  • Dual loop control of ceramic precursor extrusion batch
    Patent number: 9908259
    Abstract: A control strategy for producing high quality extrudates, including the steps of monitoring the temperature of a ceramic precursor batch by measuring the temperature of the batch material either directly or indirectly by measuring the temperature of a component of the extruder proximate to the die and transmitting the temperature data to an extrusion control system which comprises a master controller (106), at least one slave controller (110) and an optional supervisory controller. The supervisory controller determines batch temperature setpoint (102) in order to achieve the desired temperatures for extruding a certain type of batch material based on real time temperature inputs and stored parameters such as batch composition, process throughput, extruder cooling capacity, and the like.
    Type: Grant

  • Fuzzy logic control for process with large dead time
    Patent number: 7840500
    Abstract: The present invention relates to a control system, method and computer program product to control a process having a large dead time. An exemplary process controllable by embodiments according to the invention is the glass manufacturing process, where fuzzy logic is used to control a level of molten and melting raw materials in a furnace during a glass-manufacturing process by controlling the rate at which raw materials enter the furnace.
