Abstract:
In a method and device for adjusting an electro-dynamic brake of an electric camshaft adjuster for a phase angle adjustment of a camshaft of an internal combustion engine with respect to the crankshaft thereof, the phase angle is controlled by means of a position controller and the adjustment speed of the phase angle of the camshaft with respect to the crankshaft is controlled by means of an adjustment speed controller by controlling the current through the electro-dynamic brake by means of a further adjustment device and the use of Pilot controls to improve the control behavior of the cascade controller.
