A method of controlling an internal combustion engine (1) supercharged by a turbosupercharger (12) having a turbine (13) and a compressor (14); the control method including the steps of : determining, in a reduced mass flow/compression ratio graph, at least one limit operation curve (28, 30, 32, 34) of the compressor (14) representing a limit of the operating range of the compressor (14); controlling the turbosupercharger (12) to keep the actual reduced mass flow (Q AHR ) and actual compression ratio (CR) of the compressor (14) within the limit defined by the limit operation curve (28, 30, 32, 34) of the compressor (14); determining an index (”dyn) as a function of the dynamics of the reduced mass flow (Q AHR ) of the compressor (14); and modifying the limit operation curve (28, 30, 32, 34) of the compressor (14) as a function of the index (”dyn).
