Abstract

A controller controls a plurality of drives of a lifting device, wherein the controller is configured to perform a kinematic transformation of spatial position and orientation coordinates of a body and controls the drives based on the kinematic transformation. The drives can be electric drives. At least six drives are provided and regulated, so that their number exceeds the number of spatial position and orientation coordinates of the body. The lifting device is thus overdetermined.
