Abstract
A control apparatus for an internal combustion engine is provided that can precisely reflect requirements relating to performance of the internal combustion engine in a control amount of each actuator by compensating for weaknesses in the so-called torque demand control. A requirement value of each of torque, efficiency, and an air-fuel ratio, and engine information are inputted to an engine inverse model. The engine inverse model is then used to calculate actuator requirement values for achieving those requirement values. An actuator direct requirement value directly required of each of actuators is also acquired. Control of the actuators is adapted to be changed between that according to the actuator requirement value and that according to the actuator direct requirement value.
