Position regulation circuit for hydraulic setting element in automobile

摘要

The position regulation circuit has a setting piston for the hydraulic setting element (1) displaced via a position regulator (18), with the actual position of the setting element fed back to the input of the position regulator via a comparator (25).A reference model (16) is connected in parallel with the setting element, the output of the position regulator fed to one input of the reference model and to the input of a second comparator (27) connected to the input of the setting element. The outputs of the reference model and the setting element are coupled to a further comparator (28), providing an output fed to the second input of the reference model and to the input of the setting element via a proportional element (31) and the second comparator.
