An improved principle is proposed in this paper to achieve a more efficient amplitude suppression of an oscillating pendulum by a controllable moving mass. By establishing the governing equation of the pendulum with a moving mass. several suppression rules are presented to stipulate the motion parameters of the moving mass. The damping ratio is introduced to quantify the suppression e... https://safeersappliancers.shop/product-category/aeg-ckb6540acm-60cm-double-oven-dual-fuel-cooker-with-lid/
