Abstract
A method of controlling a variable geometry turbocharger is provided. A predefined desired boost pressure of a turbocharger is obtained from a memory. A predefined desired mass flow rate in an intake manifold of an engine is obtained from the memory. A theoretical amount of power required by the turbocharger to generate the desired boost pressure and the desired mass flow rate is calculated. An actual mass flow rate in the intake manifold is determined. An actual amount of power required by the turbocharger to generate the desired boost pressure and the actual mass flow rate is calculated. At least one adjustable vane of the turbine of the turbocharger is adjusted to allow the theoretical amount of power required of the turbocharger to generally equal the actual amount of power by adjusting the boost pressure.
