Deadband is a concept referring to a range of input values that do not produce any change in the output. Deadband is used to prevent system instability or unnecessary frequent oscillations, such as a thermostat not turning a heater on and off for minor temperature fluctuations.
A thermostat is set to maintain the room temperature at 20 degrees Celsius.
To avoid the heater turning on or off for every tiny temperature change,
it can be given a deadband of, for example, 1 degree.
That way, a temperature drop to 19.9 degrees will not turn on the heater,
but a temperature drop to 19.0 or lower will.
