摘要： The present invention provides a method and apparatus for controlling a fluid system. The fluid system includes a hydraulic circuit having a pump driven by an engine. The pump delivers fluid to an actuator through a valve assembly. The method includes the steps of receiving an operator input, determining a condition of the hydraulic circuit, determining a valve command in response to the circuit condition and the operator input, and delivering the valve command to the valve assembly.

摘要： A hydraulic control system for a machine having a work implement is disclosed. The hydraulic control system has a fluid actuator configured to move the work implement. The control system also has an operator interface device configured to generate at least one signal in response to a movement of the operator interface device. The control system further has a valve assembly for controllably providing hydraulic fluid flow to the fluid actuator to affect movement of the fluid actuator. The hydraulic control system has a controller configured to communicate with the valve assembly and the operator interface device. The controller is also configured to receive a signal, determine a velocity input associated with the movement of the operator interface device based on the received signal, and determine a desired fluid actuator velocity based on the determined velocity input. The controller is further configured to generate a command signal corresponding to the desired fluid actuator velocity and to direct the command signal to the valve assembly.
