Claim One:
1. A method for the suppression of vibrations ( 18 ) in a system having an actuating drive ( 14 ) for actuating a flap ( 12 ) or a valve ( 70 ) for the dosing of a gas or liquid volume flow ( 16 ), wherein a regulator output variable ( 36 ) is calculated with a regulator ( 34 ) and a control signal ( 38 ) for the actuating drive ( 14 ) is generated from the regulator output variable ( 36 ), characterized in that vibrations ( 18 ), of the flap ( 12 ) or of the valve ( 70 ) are detected by monitoring the regulator output variable ( 36 ) with a vibration detection ( 46 ), by means of an algorithm stored in a microprocessor ( 49 ) and vibrations ( 18 ) are damped 25 or suppressed by feeding the regulator output variable ( 36 ) to an adaptive filtering arrangement ( 48 ) and generating the control signal ( 38 ) by the adaptive filtering arrangement ( 48 ).
