摘要：
The invention relates to a control device which comprises a magnetic actuator (1), a final controlling element (2), a control unit (3) and a measuring device (4). The magnetic actuator (1) has a coil (10), a core (11), a spring (12) and an armature (13). The actuator (1) is connected to the final controlling element (2). The measuring device (4) determines an inductance value L of the coil (10) and produces in relation to the inductance value L a first control signal which is used to set at a hold value a theoretical value for the current through the coil (10). The current through the coil (10) is adjusted by the control unit (3) to the theoretical value when there is a pulse signal P.
