→Active Vibration Isolation (AVI) System
=== Active Vibration Isolation (AVI) System <ref name = "ref2" /> ===
It can be modeled as spring along with a feedback circuit which consists of a sensor , a controller, and an actuator. The acceleration (vibration) signal is processed by a control circuit and amplifier. Then it feeds the electromagnetic actuator, which amplifies the signal. As a result of such a feedback system, a considerably stronger suppression of vibrations is achieved compared to ordinary damping.
