Abstract:
Systems and methods according to one or more embodiments are provided for rate and position control modes used in the operations of a telescoping refueling boom system. In one example, a system includes a telescoping tube and an actuator coupled to the telescoping tube and configured to extend and/or retract the telescoping tube. A processor is coupled to the actuator and configured to select a telescoping tube rate control mode and/or a telescoping tube position control mode based on a telescoping tube current position error, a telescoping tube current rate of movement, and a value of a telescoping tube rate command.
