Method and apparatus for performing adaptive control of a position of an actuator of a positioning element

The invention relates to a method for operating a control for a positioning element system (1), in particular a throttle valve positioning element in an engine system comprising an internal combustion engine, the control is performed to obtain a manipulated variable for actuating an actuator (6) of the positioning element system (1), wherein the control by first control deviation with a transfer function (H) is applied to obtain an adapted control deviation is performed, and then the adapted control deviation with a transfer function (C) is applied to obtain the control value, wherein the transfer function ( H) represents a function, the deviation of a model (G of the model (G) of the controlled actuating encoder system (1) indicating wherein an adaptation of the control by adjusting the transfer function (H) is carried out by the parameters
