2. Hysteresis - Wikipedia

   en.wikipedia.org/wiki/Hysteresis

   The curves form a hysteresis loop. 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 single component of the moment often form a loop or hysteresis curve, where there are ...

3. Bang–bang control - Wikipedia

   en.wikipedia.org/wiki/Bang–bang_control

   In control theory, a bang–bang controller (hysteresis, 2 step or on–off controller), is a feedback controller that switches abruptly between two states. These controllers may be realized in terms of any element that provides hysteresis. They are often used to control a plant that accepts a binary input, for example a furnace that is either ...

4. Induction heating - Wikipedia

   en.wikipedia.org/wiki/Induction_heating

   Component of Stirling radioisotope generator is heated by induction during testing. Induction heating is the process of heating electrically conductive materials, namely metals or semi-conductors, by electromagnetic induction, through heat transfer passing through an inductor that creates an electromagnetic field within the coil to heat up and possibly melt steel, copper, brass, graphite, gold ...

5. Wax thermostatic element - Wikipedia

   en.wikipedia.org/wiki/Wax_thermostatic_element

   Hysteresis is the difference noted between the upstroke and down stroke curve on heating and cooling of the element. Hysteresis is caused by the thermal inertia of the element and by the friction between the parts in motion.

6. Deadband - Wikipedia

   en.wikipedia.org/wiki/Deadband

   Deadband is different from hysteresis. With hysteresis, there is no deadband and so the output is always in one direction or another. [clarification needed] Devices with hysteresis have memory, in that previous system states dictate future states. [clarification needed] Examples of devices with hysteresis are single-mode thermostats and smoke ...

7. Hysteresivity - Wikipedia

   en.wikipedia.org/wiki/Hysteresivity

   Hysteresivity derives from “hysteresis”, meaning “lag”. It is the tendency to react slowly to an outside force, or to not return completely to its original state. Whereas the area within a hysteresis loop represents energy dissipated to heat and is an extensive quantity with units of energy, the hysteresivity represents the fraction of the elastic energy that is lost to heat, and is an ...
