e/Pendulum and Hydrostat Control

Information
has gloss	eng: Pendulum and Hydrostat control is a simple system for automatically controlling the depth in water of a machine. The hydrostat senses the depth, sometimes this initially was with a simple bellows. However, with only a Hydrostat the system would tend to oscillate around the desired depth. The pendulum senses the angle at which the machine sits at relative to the vertical. The angle information is combined with the depth information in order to provide control signals to the machine's vertical-plane steering mechanism. The angle information is key in that it provides a damping term to the oscillation.
lexicalization	eng: Pendulum and Hydrostat Control
instance of	(noun) an apparatus consisting of an object mounted so that it swings freely under the influence of gravity pendulum
