  • Device for damping oscillations
    Patent number: 4395904
    Abstract: This invention relates to devices for damping oscillations in electromechanical and automatic control systems comprising actuators, various drives and flexible members providing mechanical coupling between the actuators and drive motors.In the general case the hereinproposed device furnishes a corrective signal being in phase opposition with respect to the a-c component of the signal taken from a moment or force transducer. This signal is applied to the input of the controlled drive, thereby damping mechanical oscillations. The device, according to the invention, may comprise several channels, each channel having such series-connected components as a fundamental-frequency sine-wave signal generation unit, a differentiating unit, a net time lag tuning unit, and an amplitude tuning unit.
    Type: Grant
