Abstract
A method for controlling a well pumping system is provided. The method includes the steps of entering a pump intake depth, a minimum fill preset, a maximum fill preset, and a gain value into a controller for the well pumping system, and determining a fluid over pump level. If the fluid over pump level is zero, the method calls for setting a target pump fill equal to the maximum fill preset. If the fluid over pump level is not zero, the method calls for calculating a fluid over pump ratio using the pump intake depth, and calculating the target pump fill using the fluid over pump ratio and the gain value. Further, the method includes calculating a pump fill error as the difference between the target pump fill and an actual pump fill. The method further includes controlling a pumping speed of the well pumping system based on the pump fill error.
