发明名称 Method for adapting the control of an electromagnetic actuator to operation-dictated changes
摘要 A method is provided for adapting a control for an electromagnetic actuator for actuating an adjusting device in a system, in particular for actuating a cylinder valve in a piston engine, to operation-dictated changes in the electromagnetic actuator. The electromagnetic actuator includes at least one electromagnet, a restoring spring, an armature operately coupled to the cylinder valve and disposed for movement counter to the restoring spring. The electromagnet is energized, during an idling phase of the engine, with a current having a path deviating from a normal current in a normal mode of operation. Portions of a course over time of current through the electromagnet are detected. The detected course of current is compared with a predetermined curve. The control for the electromagnet for the normal mode is adapted if there are deviations between the detected course of the current and the predetermined curve.
