Abstract
A first acceleration reference value is continuously determined by a nonlinear distance control. In parallel thereto, a second acceleration value is generated by a nonlinear velocity controller. A simple selection criterion that comprises only these two alternative acceleration values engages the second alternative acceleration reference value engagement for run up. The first alternative acceleration reference value initiates the destination braking. The second alternative reference value is used for approaching the destination position. The trip destination and the velocity of the positioning drive can be accommodate inching velocities.
