Patent ID: 7134584

Claim:
An open-loop control process for the guidance of conveyed material in a conveying device, the conveying device comprising: a) a movable means for realizing the conveyance, b) a first motion detector for measuring a first actual position value for the movable means and c) a second motion detector for measuring a second actual position value for the conveyed material, in which the control is realized with a position control having a position control clock and with a speed control having a relatively faster speed control clock, in which, in the position control clock, desired position values are preset as the command variable and, in the speed control clock, registered first actual position values are fed back to the position control and/or speed control, in which the position control is provided, at least in part, in an open-loop control part and the speed control is provided in a drive part, and in which a control variable is fed back into the position control, which control variable is dependent on second actual position values registered in the position control clock, wherein a difference deriving from the first actual position values registered in the speed control clock and the first actual position values registered in the position control clock is fed back as a further control variable to the input side of the speed control.
