CONTROL UNIT FOR CONTROL MEMBER, PRESSURE CONTROL UNIT, EGR CONTROL UNIT, AND BOOST PRESSURE CONTROL UNIT

[Problem] To provide a control processing apparatus of a control member capable of always controlling a controlled state amount in a stable manner by learning a variance of apparent efficiency caused by operation control of the control member, a pressure control processing apparatus, an EGR control processing apparatus, and a supercharging pressure control processing apparatus. [Means for Resolution] A control processing apparatus of a control member configured so as to find a target control operation amount of the control member to control a predetermined controlled state amount to be a target controlled state amount on the basis of a sum of a feedback control amount and a pre-control amount includes pre-control amount correction means for correcting the pre-control amount in such a manner that a ratio of the feedback control amount to the sum of the feedback control amount and the pre-control amount in a stable state of the controlled state amount is maintained in a predetermined range.
