Abstract
A milling machine may have a frame, ground engaging tracks that support the frame, and an actuator that adjusts a height of the frame relative to the track. The milling machine may have a control valve that selectively controls a flow of fluid into or out of the actuator based on the current supplied to the control valve. The milling machine may have a controller that determines the amount of current required to operate the actuator at a nominal actuator velocity and supplies that current to the control valve. The controller determines a measured actuator velocity based on a time required to extend or retract the actuator by a predetermined length, and adjusts the amount of current based on the measured and nominal actuator velocities. The controller also supplies the adjusted amount of current to the control valve to adjust the height of the frame relative to the track.
