Abstract (en)

[origin: WO2004007919A1] The invention relates to a control structure for the adjusting motor (8) of an electric camshaft adjuster (6) in an internal combustion engine (1). Said control structure comprises 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.
