  • noun. A property of a system such that an output value is not a strict function of the corresponding input, but also incorporates some lag, delay, or history dependence, and in particular when the response for a decrease in the input variable is different from the response for an increase. For example, a thermostat with a nominal setpoint of 75° might switch the controlled heat source on when the temperature drops below 74°, and off when it rises above 76°.

  • Word Usage
    "Such systems often exhibit hysteresis, that is multiple states for the same system parameters but which state you are in depends on history, i.e., initial conditions."
