Hysteresis in Piezoelectric Actuators: Modeling and Compensation

WebA family of hysteresis loops for grain-oriented electrical steel, a soft magnetic material. BR denotes retentivity and HC is the coercivity. The wider the outside loop is, the higher the coercivity. Movement on the loops is counterclockwise. Coercivity, also called the magnetic coercivity, coercive field or coercive force, is a measure of the ... WebA typical hysteresis loop is shown in Figure 1804a. At low electric fields and at very high electric fields a ferroelectric behaves like an ordinary dielectric with a high dielectric constant, but at the coercive field E c polarization reversal occurs and induces a large dielectric non-linearity. At zero field (E 0) the electric displacement ... shiraz inc hemet
