Embodiment Construction
[0021] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.
[0022] The main problem to be solved by the invention is to effectively suppress the lateral vibration of the cables, especially the long cables. The invention relates to a novel method and device for active variable stiffness control of cable vibration.
[0023] 1) The new method of active variable stiffness control of cable vibration is the D-V-I Bang-Bang control strategy for the multi-order modal vibration response of the cable, that is, the Bang-Bang control strategy based on the displacement-velocity product integral. The specific expression is as follows:
[0024] U ( t ) = k ∫ 0 l v ...
