In a method for regulating an excited oscillation of a system to a resonance case of the system, instantaneous values of the oscillating quantity are discretely recorded using one sampling frequency, and the sampling frequency is selected to be below twice a maximum frequency of the system. In addition, the following steps are provided: ascertaining an oscillation amplitude from the instantaneous values; regulating a control amplitude on the basis of the ascertained oscillation amplitude; specifying a control frequency on the basis of the control amplitude; generating a control oscillation in consideration of the control frequency; combining the oscillation amplitude and the control oscillation to form a control signal; and exciting the system in consideration of the control signal.
