Abstract
A method and a position control device for an electrical-fluid power drive comprising a fluid power and an electrical actuator for driving a force output point. The invention contemplates the following steps: of derivation of a target overall drive force, to be provided by the fluid power actuator and the electrical actuator jointly, for a positioning movement of the force output point to a positioning location able to be predetermined for the position control device, derivation of a target fluid drive force, to be provided by the fluid power actuator, and derivation of a target electrical drive force to be provided by the electrical actuator, on the basis of the target overall drive force in such a manner that the target electrical drive force is provided for the fractions of the target overall drive force which are more dynamic than the target fluid power drive force and for operation of the fluid power actuator in accordance with the target drive force and of the electrical actuator in accordance with the target electrical drive. The splitting of the force is preferably implemented by a high pass and a low pass.
