Abstract
A method for control of a drive for a tool or workpiece uses pilot control and a device with a control apparatus, the pilot control taking place depending on a frequency of movement. At least one of a frequency component of the reference value, a spectrum of the reference value, and a part thereof is used as the frequency of movement. At least one pilot factor is determined depending on the frequency of movement, and the at least one determined pilot factor, multiplied with a pilot value that corresponds to or is a derivative of the reference variable is used for pilot control. In this way, a contouring error can be advantageously reduced.

A method for controlling of a drive for a tool or workpiece, comprising the steps of:
- performing pilot control of the drive depending on a frequency of movement which corresponds to a reference variable,
- determining or computing at least one of a frequency component of the reference variable, and characteristic corresponding to a spectrum of the reference variable, and a part thereof,
- using the at least one of said frequency component, said spectrum, and said part thereof as the frequency of movement,
- determining at least one pilot factor depending on the frequency of movement, and
- using the at least one determined pilot factor determined, multiplied with a pilot value, for pilot control, wherein said pilot value corresponds to or is a derivative of the reference variable component values with a weight or scalar or for removing noise form said frequency.
