    Abstract: A robust automatic method to determine physical parameters for controlling a mechanical load or device (2), preferably a two-way mass oscillator, wherein a first control signal (1) is applied to a mechanical device (2) in a control circuit (3), wherein a first return signal (4) is measured, wherein the power density spectrum of the first return signal (4) is used to stipulate an excitation signal (5), preferably a broad-band excitation signal or a pseudo-random binary signal (PRBS), for the mechanical device (2), wherein the parameters are selected in such a manner that the weighted summed deviation between a frequency response of a reference model and the calculated frequency response of the mechanical device (2) is minimized, and wherein a quality or reliability indication is given for the selected parameters.
