Abstract
A spreader control system digitally filters noisy load cell measurements and inaccurate flow rate measurements to form an optimal estimate of material weight in a spreader bin. This estimate may be combined with spreader swath width and vehicle speed to determine application rate. When actuators for parameters such as apron speed or gate size are available, spreading rates may be controlled with active feedback.
