Answer» In a closed-loop control system, the part of the final control element that translates the control signal into action by the control device. An actuator is a component of a machine that is responsible for moving or controlling a MECHANISM or system. An actuator requires a control signal and a source of energy. The control signal is relatively low energy and may be electric voltage or current, PNEUMATIC or HYDRAULIC pressure, or even HUMAN power.
