Abstract
A system includes two guides that extend parallel to each other and a beam that extends transverse to the guides. The beam is movable over the guides, with a slide being movable over the beam. In controlling the system, a first difference is determined between desired and actual positions of the beam on the first guide. A second difference is determined between desired and actual positions of the beam on the second guide. A position difference between desired and actual positions of a point on the beam is determined on the basis of the first and second differences. A variation between the first and second differences is determined on the basis of the first and second differences. The force and torque to be exerted on the beam are determined at least in dependence on the position difference, variation, and position of the slide relative to the beam's center of mass.
