20080197228 | METHOD AND APPARATUS FOR FRICTION COMPENSATION - For friction compensation in a winding machine, with which a material is wound onto a winding drum, and the winding drum is driven by a winding drive which is triggered by a control/regulating device, and in the control/regulating device a driving torque of the winding drive is specified, in a friction compensation unit, as an input-side process parameter, a winding speed of the winding drum is taken into account, in order to compensate for the frictional moment, and at least one additional process parameter is taken into account. An apparatus for friction compensation in a winding machine, with which a material is windable onto a winding drum, and the winding drum is driven by a winding drive which is triggerable by a control/regulating device, has a tensile stress regulator and a diameter calculation unit and/or a friction compensation unit for linearizing the tensile stress regulator located in the control/regulating device, and in the friction compensation unit, a winding speed of the winding drum is imposed, in which to compensate for the frictional moment in the friction compensation unit, at least one additional process parameter is imposed as an input-side process parameter. | 08-21-2008 |
