Abstract
A control apparatus for an internal combustion engine is provided that is capable of calculating a high-accuracy turbine rotational speed. A turbo supercharger which includes, in an exhaust passage, a turbine that is operated by exhaust energy of the internal combustion engine. A turbine rotational speed model which calculates a turbine rotational speed. The turbine rotational speed is corrected by an exhaust energy correction part equipped with the turbine rotational speed model.
