A control apparatus is provided for a multi-cylinder internal combustion engine that includes a plurality of cylinders, an exhaust passage, and an exhaust gas recirculation device including passages through which a part of exhaust gas discharged into the exhaust passage is recirculated individually to the respective cylinders. The control apparatus includes a control unit configured to execute an air-fuel ratio feedback control for controlling an exhaust gas air-fuel ratio to a target air-fuel ratio through feedback using a feedback correction amount. The control unit is configured to identify the cylinder corresponding to the passage in which a clogging occurs, among the plurality of passages, in a case where the clogging occurs in the passage among the plurality of passages, and to set the target air-fuel ratio according to a deviation of the feedback correction amount, the deviation corresponding to the identified cylinder. |
