    摘要: A hydraulic system, and associated method of control, includes an operator input device, a source of hydraulic fluid flow, and a plurality of actuators. At least one valve associated with each actuator for controlling a flow of fluid to and from the actuator. A controller is responsive to a signal from the operator input device to calculate a hydraulic pressure to be supplied to each of the actuators. The controller controls the source of hydraulic fluid flow and the valves for powering the actuators with the calculated hydraulic pressure. The controller also monitors a sensed parameter to determine whether the actuators can be powered with the calculated hydraulic pressure, and in response to a determination that the actuators cannot be powered with the calculated hydraulic pressure, calculates a discrepancy ratio and modifies actuation of the actuators with the discrepancy ratio.

    摘要: A hydraulic circuit includes at least one actuator that may be powered for performing a function. A plurality of valves are associated with the at least one actuator for controlling a flow of fluid into and out of the at least one actuator. The hydraulic circuit also includes multiple pumps for supplying fluid to the at least one actuator. The multiple pumps includes a first pump for primarily powering the at least one actuator for movement in a first direction and a second pump for primarily powering the at least one actuator for movement in a second direction, opposite the first direction.
