A control structure for the adjusting motor ( 8 ) of an electric camshaft adjuster ( 6 ) in an internal combustion engine ( 1 ) is provided. The control structure includes a controller ( 19 ) which processes measuring signals of the internal combustion engine ( 1 ) to control data for the adjusting motor ( 8 ). A controller ( 19 ) which has meaningful values for the adjusted setpoint rotational speed of the adjusting motor ( 8 ), even when the input differential signal has a zero value, is obtained by applying the signal of an uncontrolled rotational speed ( 21 ) to the output signal ( 20 ) of a controlled setpoint rotational speed.
