1. An apparatus associated with compensating boost pressure in a charged internal combustion engine, comprising:
an electronic control unit having a correction module, the electronic control module being configured to cooperate with at least two actuators, wherein a first of the at least two actuators having a first system gain, and a second of the at least two actuators having a second system gain that differs from the first system gain, wherein
the correction module is configured such that firstly at least one controller parameter is smoothed within a defined transition range, and secondly an the integrative component of an adjustment position with respect to an opening area of a respective actuator is transferred with a correction value corresponding to a ratio of or the difference between the system gains when the control passes from the first of the at least two actuators with the first system gain to the second of the at least two actuators with the second system gain.
