  "textContent": "Method to control an electromagnetic actuator (22) of an internal combustion engine (ICE), in particular for a fuel pump (4) of a direct-injection system; wherein the electromagnetic actuator (22) is controlled by means of an electric current pulse of the Peak&Hold type, i.e. subdivided into a peak phase and a hold phase; the method comprises: acquiring the initial duration of the peak phase (T START , T), during which a peak control current (I) is to be supplied to the electromagnetic actuator (22) to control the movement of a component (21, 25) of the electromagnetic actuator (22) moving towards a position defined by a limit stop (26); and determining the duration of the peak phase (T) by progressively decreasing the initial duration of the peak phase (T START , T) by a first change (T P1 ).",
