Abstract

A motion control system operating a machine as well as a method operating a machine scale a motion path section-by-section by using a C²-consistent scaling function.

Claims

1. A method for operating a motion control system of a machine, comprising scaling a motion path section-by-section by using a C²-consistent scaling function.

2. The method of claim 1, further comprising determining with a spline algorithm corner points of a polygon which include the C²-consistent scaling function and determine the course of the C²-consistent scaling function, with the corner points ensuring a monotonic course of the C²-consistent scaling function and a homogeneous curvature distribution along the C²-consistent scaling function.

3. A computer program comprising program code stored on a non-transitory storage device, wherein the computer program when executed on a control device of a motion control system of a machine, scales a motion path section-by-section by using a C²-consistent scaling function.

4. A computer program product comprising program code stored on a non-transitory computer-readable data carrier, wherein the computer program when executed on a control device of a motion control system of a machine, scales a motion path section-by-section by using a C²-consistent scaling function.

5. A motion control system of a machine, comprising a processing unit and a memory, wherein a computer program when loaded into the memory and executed on the processing unit, causes the processing unit of the motion control system to scale a motion path section-by-section by using a C²-consistent scaling function.
