<p>A control apparatus for an internal combustion engine configured to control the internal combustion engine is provided with: a first F/B controlling device configured to perform first F/B control in which an air-fuel ratio of a gas flowing into a three way catalyst converges to a target air-fuel ratio, on the basis of an output value of an air-fuel ratio sensor; a second F/B controlling device configured to perform second F/B control in which the target air-fuel ratio or the output value of the air-fuel ratio sensor is corrected such that an output voltage value of an oxygen concentration sensor matches a target output value; a learning device configured to learn an output characteristic of the oxygen concentration sensor; and a target value setting device configured to set the target output value according to a learning value of the output characteristic.</p> |
