Abstract: A method for driving at least one rotor in a planar drive system. The rotor has a device for generating a magnetic field. The rotor can be moved on a drive surface formed by stator modules comprising a magnetic field generator. A virtual two-dimensional potential curve is determined for the rotor, with a target point having an attractive potential. A virtual force vector is determined with a vector direction and a vector length at a first position of the rotor, which is determined from the virtual two-dimensional potential curve. A magnetic drive field interacting with the magnetic field of the rotor is generated by the magnetic field generator such that a resulting force is applied to the rotor by interaction of the magnetic drive field with the magnetic field. The direction of the resulting force is based on the vector direction, and the strength is based on the vector length.

Abstract: A machine control system including a first data processing device having a first central processing unit, which implements a control agent, the first data processing unit communicating control commands to the machine and receiving process and environmental data from the machine, which contain state information about the state of the machine and/or an environment of the machine.
