Dynamic hysteresis
WebThe study of hysteresis can be traced back to the 19th century. The key characteristics of hysteresis are rate independence and rate dependence. A typical system with hysteresis characteristics is the reducer. In the industrial sector, the hysteresis phenomenon of a reducer is often illustrated by the lost motion, which is always consistent with the rate … WebJan 1, 2004 · A viscous-type dynamic hysteresis model (DHM) is developed. The DHM is compatible with static underlying model of any type and nature (Preisach or non-Preisach). The distinguishing features of...

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". It was coined in 1881 by Sir James Alfred Ewing to describe the … See more Rate-dependent One type of hysteresis is a lag between input and output. An example is a sinusoidal input X(t) that results in a sinusoidal output … See more Magnetic hysteresis When an external magnetic field is applied to a ferromagnetic material such as iron, the atomic domains align themselves with it. Even when the field is removed, part of the alignment will be retained: the material has become … See more WebMar 1, 2024 · Compensating the dynamic hysteresis of the piezoelectric actuator can not only improve its positioning accuracy under open-loop control, but also help establish a high-precision closed-loop control system. At present, designing a feedforward inverse compensator is a common method for hysteresis compensation.
