Abstract
A rotating element control system includes a rotating element rotatably disposed on a main body, a first measuring unit which measures an angular movement of the main body, a driving unit which drives the rotating element, a second measuring unit which measures a rotational speed of the rotating element, a transfer unit which connects the rotating element and the driving unit and transfers a driving force to the rotating element, a motion compensation unit which generates a compensation signal which removes an error component generated by the angular movement of the main body, and a stabilization control unit which controls the driving unit based on the compensation signal and a difference between an input signal and the rotational speed of the rotating element.
