'automatically-regulated' originates from the combination of 'automatic' and 'regulate', where 'automatic' comes from Greek 'automatos' meaning 'self-moving', and 'regulate' from Latin 'regulare' meaning 'to control'.

'automatically-regulated' evolved from the concept of 'automatic regulation' in the 20th century, combining the ideas of self-operation and control.

Initially, it referred to mechanical systems that adjusted themselves, but now it includes digital and electronic systems.
