A method to control a supercharged internal combustion engine by means of a turbocharger provided with a turbine and a compressor which compresses the air taken in; the control method includes the steps of determining the instantaneous rotation speed of the turbocharger; and calculating the average power delivered by the turbine as a function of the absolute value of the j-th harmonic component of the instantaneous rotation speed of the turbocharger and of the instantaneous rotation speed of the turbocharger; and controlling the supercharged internal combustion engine as a function of the average power delivered by the turbine.
