摘要： A method for controlling a fuel metering device with a movable metering element, comprising at least two iterations of the following steps:



a detection (E1) of a possible change in the operating state among two position sensors of the metering element, if no change in the operating state is detected, a determination (E2_1) of the position of the metering element from an average of the measurements of the sensors or otherwise a determination (E2_2) from the non-defective sensor,
a determination (E4) of a fuel flow rate setpoint, a conversion (E5) of the flow rate setpoint,
a determination (E6) of a command of displacement of the metering element, a control (E7) of the position of the metering element, and




if a change in the operating state is detected, the calculation of an instantaneous fuel flow rate from the position of the metering element, and, during the second iteration of the method, the determination of the flow rate setpoint according to instantaneous flow rate to match the position setpoint to the position of the metering element.
