Swing control algorithm for hydraulic circuit

A fluid control system may comprise a pump, a tank, and an actuator including a working chamber. The system may be operative to control rotational movement of a swing structure and movement of an least one implement. A valve assembly may be configured to control fluid communication between the worki...

Zusammenfassung:	A fluid control system may comprise a pump, a tank, and an actuator including a working chamber. The system may be operative to control rotational movement of a swing structure and movement of an least one implement. A valve assembly may be configured to control fluid communication between the working chamber and the tank and to control fluid communication between the working chamber and the pump. An input device may be operative to selectively control movement of the swing structure. The system may include a controller in communication with the valve assembly and the input device. The controller may be configured to control a flow condition of the working chamber through a sensed pressure condition of the working chamber and a command from the input device.
