Abstract

The invention relates to controlling of a work machine based on sensed variables. The mobile work machine includes a frame and a ground engaging element movably supported by the frame and driven by anengine to drive movement of the mobile work machine. The mobile work machine includes a container movably supported by the frame, the container configured to receive contents and an actuator configured to controllably drive movement of the container relative to the frame. The mobile work machine includes a control system configured to generate an actuator control signal, indicative of a commandedmovement of the actuator, and provide the actuator control signal to the actuator to control the actuator to perform the commanded movement and a content density determination system, communicativelycoupled to the control system, configured to determine a density of the contents of the container.
