Thermodynamic hysteresis

    In phase transitions, the transition from one state to another is not linear with the energy supplied or absorbed. Hysteresis can be used to filter out unwanted signals in control systems, taking into account the recent history of the signal. For example, in thermostatic controls, a heating element (a boiler) is turned on when the temperature falls below a value T1, but is not turned off until a temperature T2 greater than the first one is exceeded. This prevents unwanted switching due to inaccuracy and small fluctuations around a single threshold.
