Abstract
To control movement of a transport unit of a linear motor, a quality functional J(SG) with quality terms JT(SG) is used as a function of manipulated variables (SG) of active drive coils. The quality functional J(SG) controlling movement of the transport unit along the stator is optimized with regard to the manipulated variable (SG) to determine optimal manipulated variables (SG) for the relevant time step of the control of movement, active drive coils are energized according to the determined optimal manipulated variables (SG), and at least two movement phases are provided during the movement of the transport unit along the stator. In the at least two novement phases, different quality functionals J(SG) are used for determining the optimal manipulated variables (SG), the different quality functionals J(SG) differing by the number k of the quality terms JT(SG) used and/or by the quality terms JT(SG) and/or by the weighting factors k.
