Abstract
An electric drive fuel control system and method for controlling a total drive torque supplied to a fuel metering pump includes a first main drive motor, a second main drive motor, and a backup drive motor, all coupled to the fuel metering pump. The operability of a main motor control to control electric current supply to the first main drive motor or the second main drive motor is determined. If the main motor control is operable, the total drive torque to the fuel pump is supplied from the backup motor and either the first main drive motor or the second main drive motor. If the main motor control is inoperable, the total drive torque to the fuel pump is supplied from only the backup drive motor.
