It is an electronic control system where controlling mechanism like hydraulic, pneumatic, etc. is actuated and controlled by a low-energy signal.
control system that converts a small mechanical motion into one requiring much greater power; may include a negative feedback system
a control that is external to the system and that acts on the feedback loop to modify its value
a device that is capable of positioning it's mechanical actuator to a specified position
An automatic device for controlling large amounts of power by means of small amounts of power.
An automatic feedback device in which the controlled variable is mechanical position or any of its time derivatives.
Electromechanical means of automatically maintaining a desired state by sensing variations from that state, and then correcting those variations by using very small amounts of power to control much larger amounts of power.
A tracking device that continuously follows some variable quantity, using its own feedback to maintain a constant rate, temperature, or rotation. Automated temperature-control devices are examples, as are the focus and tracking servos of optical disk drives. (7/96)
A servomechanism, usually shortened to servo, is a device used to provide mechanical control at a distance. For example, a servo can be used at a remote location to proportionally follow the angular position of a control knob. The connection between the two devices is not mechanical, but electrical or wireless.
