Abstract
A pendulum includes a movable body connected to a stationary supporting structure for oscillation in a fixed vertical plane. The pendulum further includes a control and stabilization system for controlling and stabilizing the oscillation amplitude of the movable body. The control and stabilization system includes a braking device which includes a permanent magnet and an electrically conductive element, one of which is attached to the movable body and the other of which is connected to the supporting structure such that when the movable body approaches one end of the oscillation field, the generated magnetic flux causes a braking of the movable body's motion. The quality factor Q of the pendulum is substantially proportional to the inverse of a power, at least equal to the square, of the amplitude of the oscillation of the movable body with the amplitude is close to the desired amplitude of oscillation.
