ser·vo·mech·a·nism

 (sûr′vō-mĕk′ə-nĭz′əm)
n.
1. A feedback system that consists of a sensing element, amplifier, and servomotor, used in the automatic control of a mechanical device.
2. A self-regulating feedback system or mechanism: "We do not need to know in detail how the minute chemical servomechanisms of the muscles operate in order to move our arms" (Harper's).

servomechanism

(ˈsɜːvəʊˌmɛkəˌnɪzəm; ˌsɜːvəʊˈmɛk-)
n
(Electrical Engineering) a mechanical or electromechanical system for control of the position or speed of an output transducer. Negative feedback is incorporated to minimize discrepancies between the output state and the input control setting
