DISTANCE BASED ACTUATOR VELOCITY CALIBRATION SYSTEM
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.
一种铣刨机可具有框架、支承框架的地面接合履带以及调整框架相对于履带的高度的致动器。铣刨机可具有控制阀，该控制阀基于供应到控制阀的电流选择性地控制流体流入或流出致动器。铣刨机可具有控制器，所述控制器确定以标称致动器速度操作致动器所需的电流量，并将该电流供应到控制阀。控制器基于将致动器延伸或缩回预定长度所需的时间来确定测量的致动器速度，并且基于测量的致动器速度和标称致动器速度来调整电流量。控制器还向控制阀供应经调整的电流量，以调整框架相对于履带的高度。
