Claim Text:
1. A control device comprising a sensor unit suitable for outputting a measurement signal representing a deflection of an oscillator along a direction of excitation, an actuator unit acting on the oscillator, which is controllable by control signals, characterized by a controller main unit which is configured to deduce from the measurement signal and a harmonic set point signal a control signal for the actuator unit such that the actuator unit counteracts a deviation of the deflection of the oscillator from a set amplitude of a harmonic resonance oscillation of the oscillator, and a controller extension unit which is configured to determine at deactivated actuator unit from the measurement signal an actual phase and an actual-amplitude of a residual oscillation of the oscillator and to output to the controller main unit a harmonic set point signal adapted to the actual phase and the actual-amplitude such that after activating the actuator unit an amplitude of the residual oscillation of the oscillator is amplified phase synchronously up to the set amplitude and such that in this process energy contained in the residual oscillation is used.
