  • Servocontrol process for a servovalve which can be servocontrolled in terms of flow rate and pressure
    Patent number: 5915401
    Abstract: A process for automatically controlling a hydraulic servovalve with a hydraulic slide valve displaced by a rotary actuator. The process includes a first loop for automatically controlling the delivery as a function of the measurement of the angular position of the rotary actuator and a second automatic control loop with variable control as a function of the pressure measurement. The first automatic control loop is a proportional action loop whose increase is constant for the absolute values of the pressure deviation which are less than at least a threshold value and then varies in an increasing manner for absolute values of the pressure deviation which are greater than the same threshold.
