1. The method of controlling the value of an operating parameter of an engine as a function of at least one engine operating condition, the engine having an actuator responsive to a control signal for adjusting the operating parameter after a known delay time to a desired value, the method comprising the steps of:

  • determining the value of the engine operating condition;

    determining the variation of the engine operating condition;

    predicting the value of the engine operating condition at a future time based on the determined value and variation of the engine operating condition;

    determining the desired value of the engine operating parameter corresponding to the predicted value of the engine operating condition;

    determining the value of a control signal required to establish the desired value of the engine operating parameter;

    providing the control signal at the determined value to the actuator at a time that precedes the future time by the known delay time, whereby the desired value of the engine operating parameter is established at the future time at which the corresponding predicted value of the engine operating condition was to occur.
