Existing hysteresis models are complicated, or inaccurate in describing dynamic hysteresis with force-voltage coupling. To solve this problem, a …
Hysteresis can be a dynamic lag between an input and an output that disappears if the input is varied more slowly; this is known as rate-dependent hysteresis. However, phenomena such as the magnetic hysteresis loops are mainly rate-independent, which makes a durable memory possible. See more Hysteresis is the dependence of the state of a system on its history. For example, a magnet may have more than one possible magnetic moment in a given magnetic field, depending on how the field changed in the past. Plots of a … See more Control systems In control systems, hysteresis can be used to filter signals so that the output reacts less rapidly than it … See more Elastic hysteresis In the elastic hysteresis of rubber, the area in the centre of a hysteresis loop is the energy dissipated … See more Cell biology and genetics Hysteresis in cell biology often follows bistable systems where the same input state can lead to … See more The term "hysteresis" is derived from ὑστέρησις, an Ancient Greek word meaning "deficiency" or "lagging behind".
