摘要:
A method for adjustment of the relative angle of rotation between a camshaft and a crankshaft in an internal combustion engine through an electromechanical phase adjuster is provided. The invention provides a rapid and precise adjustment behavior. To that end, a deviation of the adjustment speed (DeltaOmega) between a desired adjustment speed (OmegaSOLL) and an actual adjustment speed (OmegaIST) is calculated from at least one measurement parameter in a second control loop cascaded below the first control loop. An output parameter is calculated dependent on the deviation of the adjustment speed (DeltaOmega) through an adjustment speed adjuster ( 26 ) cascaded below the angle of rotation adjuster ( 23 ), with the output parameter being used to adjust the angle of rotation (Phi) using an electromechanical actuator ( 14 ). The relative angle of rotation can be rapidly and precisely adjusted by adjusting the adjustment speed. A phase adjuster for controlling the relative angle of rotation is
