A method for controlling an internal combustion engine (1) supercharged by means of a turbocharger (12) provided with a turbine (13) and with a compressor (14); the control method includes the steps of determining a pressure objective downstream of the compressor (14); determining a critical threshold (M critica ) of the reduced mass flow rate (Q AHR ), said critical threshold (M critica ) delimiting, on a reduced mass flow rate/compression ratio plane, a critical area close to the achievement of sonic conditions; and filtering, by means of a first filter, the pressure objective downstream of the compressor (14) when the current reduced mass flow rate (Q AHR ) is higher than the critical threshold (M critica ). |
