摘要:
A pressure compensator for use in a control system for an electro hydraulic-implemented work element being operated through the use of operator input control mechanisms generating operator input signals upon the application thereof, the control system including an actuator coupled thereto for controlling the operation thereof, the pressure compensator determining a pressure compensator coefficient to be applied to an operator input signal to compensate for changes of pressure drop across a valve in communication with the actuator. The pressure compensator coefficient is used to produce an input flow control signal for inputting to the valve to control the amount of hydraulic fluid that flows therethrough to the actuator so that a desired velocity of the actuator is achieved.
