Abstract
An air flow calibration system for an agricultural system includes a controller configured to receive first sensor signals indicative of a set of upstream air pressures and second sensor signals indicative of downstream air pressures. The controller is also configured to iteratively determine a variance delta based on the pressures, compare the variance delta to a threshold value, and output a first output signal to decrease an air flow rate by a first amount until the variance delta is greater than the threshold value. The controller is configured to iteratively output a second output signal to increase the air flow rate by a second amount, determine the variance delta, and compare the variance delta to the threshold value until the variance delta is less than or equal to the threshold value. The controller is configured to determine a plugging condition is terminated, and store a calibration value.
