Abstract
The invention relates to an open-loop control process for the motional guidance of conveyed material (32) in a conveying device (30) and to a corresponding conveying device (30). The conveying device (30) has a movable means (36) for realizing the conveyance and a first motion detector (42) for measuring a first actual position value (x1act) for the movable means (36) and a second motion detector (40) for measuring a second actual position value (x2act) for the conveyed material (32). The control is herein realized with a position control having a position control clock (Tpc) and with a speed control (GR) having a relatively faster speed control clock (Tsc), in which, in the position control clock (Tpc), desired position values (xcmd) are preset as the command variable and, in the speed control clock (Tsc), registered first actual position values (x1act) are fed back to the position control, in which the position control is provided, at least in part, in an open-loop control part (NC) and the speed control (GR) is provided in a drive part (A), and in which a control variable (R) is fed back into the position control, which control variable is dependent on second actual position val…
