A method controls an internal-combustion engine (1) supercharged by a turbocharger (12) and including a turbine (13) and compressor (14). The control method includes steps of determining a pressure objective downstream of the compressor (14), determining a critical threshold of a reduced-mass-flow rate that delimits on a “reduced-mass-flow rate/compression ratio” plane a critical area substantially close to achievement of sonic conditions, and filtering by a first filter the pressure objective downstream of the compressor (14) when a current reduced-mass-flow rate is higher than the critical threshold. |
