Abstract
A work vehicle includes a frame; an implement; a linkage assembly mounting the implement to the frame; a linkage actuator coupled to the linkage assembly and the frame and configured to reposition the linkage assembly relative to the frame; a sensor configured to generate sensor position data associated with at least one of the linkage assembly and the linkage actuator representing a linkage position; an operator interface configured to receive operator input from an operator associated with the linkage actuator representing a velocity request; and an electronic control system having processing and memory architecture operatively coupled to the sensor, operator interface, and linkage actuator. The electronic control system is configured to generate an actuator command for the linkage actuator based on the velocity request and the linkage position that, upon execution, results in a constant velocity of the implement for the operator input regardless of the linkage position.
