Abstract
A method for a turbocharger of a heat engine including a turbine, a compressor, and a by-pass actuator that can be used to control an air flow that does not pass through the turbine. The method includes determining a position set point of the by-pass actuator as a function of a compression ratio set point, a compression ratio measurement, a measurement of the rate of flow through the compressor, a measurement of the pressure downstream from the turbine, a measurement of the pressure downstream from the compressor, a measurement of the temperature upstream from the turbine, and a measurement of the temperature upstream from the compressor. The method can be used to control a supercharging device with a single or dual turbocharger.
