  • SERVO SYSTEM USING FEEDBACK
    Publication number: 20090178551
    Abstract: A servo control system comprising a hydraulic actuator, a position sensor and a hydraulic control valve. The hydraulic actuator is coupled to a gas controlled valve. The position sensor measures the position of the hydraulic actuator and sends the position of the actuator as an input to an engine control unit (ECU). The hydraulic control valve is coupled to a proportional solenoid coupled to the ECU. When the ECU senses the position of the hydraulic actuator and in response to a control input, the ECU commands the position of the hydraulic control valve by controlling the force of the proportional solenoid and the hydraulic fluid sent to the hydraulic actuator, actuating the hydraulic actuator to move to a desired position and actuate the gas controlled valve.
