In this paper, the experimental setup of a pendulum with a moving mass is established to study the rapid suppression of pendulum oscillation. The intermittent motion of the moving mass is employed to achieve more efficient suppression. The proposed control method can reduce mass motion distance rapidly in the vicinity of the vertical position to ensure the stability of the system. The mass motion is triggered by recognizing the pendulum angle in real time so that the nonsynchronous motion can be avoided. With the verification of the accuracy of the controlled motion distance, the effects of several motion parameters of the moving mass are studied. Moreover, the experimental results reveal that the proposed control strategy is more efficient in oscillation suppressing than the traditional continuous control method. The experimental setup and the proposed approach can be applied in pendulum-like structure design and oscillation control.

基于间歇质量运动的摆的快速振荡抑制实验研究

在本文中，建立了具有运动质量的摆的实验装置，以研究摆振动的快速抑制。运动质量的间歇运动被用来实现更有效的抑制。所提出的控制方法可以在垂直位置附近迅速减小质量运动距离，以确保系统的稳定性。通过实时识别摆角来触发质量运动，从而可以避免非同步运动。通过验证受控运动距离的准确性，研究了运动质量的多个运动参数的影响。此外，实验结果表明，所提出的控制策略在抑制振荡方面比传统的连续控制方法更加有效。
