Abstract
A method for controlling load dependent valve flow rate in a presence of an overrunning load in a bucket includes receiving a measured pressure from and/or to a hydraulic valve, and the hydraulic valve is coupled to an actuator coupled to the bucket. The method includes calculating a load pressure on the actuator based on the measured pressure. The method includes receiving a first valve command for actuating the actuator to lower the bucket, the first valve command being associated with a desired valve flow rate and a desired maximum speed of the actuator. The method includes providing a second valve command based on a last calculated load pressure before receiving the first valve command, wherein the second valve command adjusts a valve opening area of the hydraulic valve so that a speed of the actuator corresponds to a maximum speed of the actuator for the last calculated load pressure.
