Abstract: A self-snubbing hydraulic actuation system includes a hydraulic motor, a component actuator, a control valve, a valve actuator, and a variable resistance device. The hydraulic motor is configured, upon receipt of hydraulic fluid, to rotate and supply a drive torque. The component actuator is configured, upon receipt of drive torque from the motor, to translate to a position. The control valve is movable to a plurality of valve positions to thereby control hydraulic fluid flow rate to the hydraulic motor. The valve actuator is coupled to the control valve and is adapted to receive electrical current and to move the control valve to a valve position based on the magnitude of the received electrical current. The variable resistance device is configured, based on component actuator position, to selectively vary the magnitude of the electrical current received by the valve actuator.
