  • CONTROLLING AN ELECTRICALLY-DRIVEN ACTUATOR
    Publication number: 20150042255
    Abstract: In some aspects, an actuation system includes an electrical positioning driver and an electrically-driven actuator. A voltage boost converter in the electrical positioning driver receives an input voltage. The voltage boost converter passes the input voltage to a voltage bus in the electrical positioning driver. The voltage on the voltage bus is converted to an actuator power signal that controls the electrically-driven actuator. The voltage boost converter boosts the voltage on the voltage bus to control a mechanical output performance of the electrically-driven actuator.
