  • Publication number: 20250134089
    Abstract: Methods and systems are provided for controlling the level relative to ground of moveable wings in a spray system that includes the moveable wings mounted to a common center frame support structure attached to an associated work vehicle to form a pair of opposed independently moveable wings extending laterally from the associated work vehicle. An initial control signal is determined for moving the moveable wings based on positions of the moveable wings relative to the ground. A compensating signal is determined for compensating the initial control signal, wherein the compensating signal is derived independent from the position of the moveable wings relative to the ground and includes a flexure component dependent upon one or more flexural properties of the associated work vehicle. A level control output signal is generated for controlling the level of the moveable wings based on a combination of the initial control signal and the compensating signal.
