In industrial papermaking equipment, the calender rolls must be precisely controlled to achieve the right degree of smoothness and glossiness in the paper. Typically, roll posi- tions must be maintained within a tolerance of 0.1 millimeters, and the pressure at the nip—the line of contact between rolls—must be within 0.2 bar of its set value. Using Model-Based Design, Metso devel- oped a digital hydraulic system that meets these requireme
