A turbo supercharger (20) which includes, in an exhaust passage (14), a turbine that is operated by exhaust energy of the internal combustion engine (10). A turbine rotational speed model (70) which calculates a turbine rotational speed Ntb. The turbine rotational speed Ntb is corrected by an exhaust energy correction part (72) equipped with the turbine rotational speed model (70).",
