English abstract:
Active vibration damping of flexible structures requires the positioning of actuators and sensor along the structure. When the actuators become particularly small in comparison to the structure a large number of modes is necessary to accurately represent the response of the structure. Neglecting these higher modes may result in a spillover phenomenon which is capable of destabilizing the closed loop system. Therefore proper correction methods to account for the dynamics of higher modes in the structural model have to be found. One such possibility is the utilization of Frequency Response Mode (FRM), a special form of the particular solution of the equations of motion of a flexible structure. Inthis paper the FRM is defined and used for model correction of a smply supported beam. Finally, correction terms are used to quantize local actuator action.
