Abstract
An end effector leveling system for moving an end effector of a work machine with a boom assembly, a plurality of sensors, an input interface, and a controller. The plurality of sensors are configured to sense a current movement speed of the hoist boom, the stick boom, and the end effector. The input interface is configured to receive an end effector target angle input command for movement of the end effector at a constant target angle. The controller receives command signals from the input interface, determines based on the command signals a target tilt actuator velocity for actuating the tilt actuator, and an actual tilt actuator tilt velocity actuator and command the tilt actuator to move such that the end effector moves with an aggregate velocity derived from a weighting function of the target tilt actuator velocity and the actual tilt actuator velocity.
