摘要
A positioning - device (1) has an actuator (3) for adjusting a position (x) of a component (6) to be positioned on. An output variable (fout) of the actuator (3) has a non-linear dependence on the position (x). For the control of the actuator (3) is a control device (10) is provided, which as a rule, a position unit (11) and a compensation unit (13) comprises. The compensation unit (13) is designed in such a way that, in dependence on the position (x) a compensation - correcting variable (iR) for the control of the actuator (3) is provided, so that the non-linear a function of the output variable (fout) from the position (x) is compensated.
