Abstract: Systems and methods for controlling a vertical pumping unit are provided. The method includes a self-learning phase and a running phase, wherein the self-learning phase includes obtaining a self-learning result and the running phase includes controlling a motor of the vertical pumping unit to run according to the self-learning result and preset running parameters. The method enables the vertical pumping unit to adjust running parameters of the running phase according to the self-learning results, avoid the accumulation of errors effectively so that changes in stroke length and stroke frequency caused by the motor V-belt, load belt extension and retraction and other elastic links are limited to a minimum range so as to ensure the running accuracy of the vertical pumping unit.
