Abstract
A hysteresis compensation method, in which a hysteresis error is calculated for an obtained weighing value by means of an ideal hysteresis error model, and an ideal compensation value is further calculated by means of an ideal hysteresis compensation model, wherein by using a proportional relationship between a system hysteresis error model established in hysteresis calibration and the ideal hysteresis error model, the ideal compensation value is corrected to a final compensation value. The method establishes a mapping relationship between the system's own hysteresis compensation and the ideal state hysteresis compensation, and realizes the transformation of a complicated hysteresis error compensation situation into an ideal hysteresis error compensation situation. The method not only has a good compensation effect for the hysteresis error compensation under ideal situations, but also can obtain an excellent hysteresis compensation effect under complicated hysteresis situations.
