  • Actuator control for force fight mitigation
    Patent number: 12151804
    Abstract: A system and method for controlling two or more actuators acting together to move a component or surface includes Two or more actuators engaged with the component or surface to be moved. Each actuator is displaceable to move the component or surface in response to a component or surface position command. Each actuator has an associated actuator controller to receive the position command and to output an actuator displacement command. The system also includes force fight control means configured to determine a force differential from forces, or a pressure differential from pressures measured at each actuator and to derive a speed and/or a current offset signal, and to provide the offset signal to the actuator controllers to modify the actuator displacement commands.
