  • Patent number: 11634293
    Abstract: The present invention provides an adaptive control system to control a plant using direct output feedback in which a function of the full plant state, as opposed to estimates thereof, is used for feedback control of the plant. The adaptive control system of this invention is therefore highly useful in the control of plants, particularly plants for controlling the physical properties of rolls of web material and more particularly a calendering apparatus. Accordingly, in a particularly preferred embodiment the adaptive control system of this invention controls loading of a calender apparatus, such as a pair of opposed rolls forming a calendering stack, based upon the physical properties of a previously processed web.
    Type: Grant

    Assignee: Kimberly-Clark Worlwide, Inc.
    Inventors: Ryan A. Petras, Matthew W. Trautschold, Mark G. Dollevoet, Vivek M. Karandikar, Julie A. Hansen, Walter F. Montgomery, Antwain Taylor, Kevin B. Sartain, Justin P. Stergar
