Abstract

In order to reduce the excitation of vibrations and resonances in a test bed for a real component and a virtual component, one of the following method steps is provided: a) determining a first correction value (K1) from the measured variable (M), wherein the first correction value (K1) is added to the measured variable (M) and the sum is communicated as a corrected measured variable (M*) to the virtual component for calculating the control variable (S), b) determining a second correction value (K2) from the calculated control variable (S), wherein the second correction value (K2) is added to the calculated control variable (S) and the sum is transferred as a corrected control variable (S*) to the actuator, c) determining a third correction value (K3) from the measured variable (M), wherein the third correction value (K3) is used to modify a parameter (P) of the equation of movement.
