Abstract
A method for controlling a hydraulic system includes receiving an operator command signal via an operator command input device; receiving a throttle position signal from a throttle; retrieving from a memory a first predetermined correlation between the operator command signal and a corresponding command flow rate; retrieving from the memory a second predetermined correlation between the throttle position signal and a corresponding available flow rate from a hydraulic pump; determining the command flow rate based on the first predetermined correlation and the operator command signal; determining the available flow rate based on the second predetermined correlation and the throttle position signal; and providing a control signal based on the available flow rate and the command flow rate.
