| 摘 要： | 由于某些情况下拉索的抗弯刚度对振动频率有一定的影响,文章在考虑拉索抗弯刚度的基础上,建立了刚性拉索振动主动控制模型;融合线性二次型最优控制(LQR)策略和传统的Bang-Bang单模态控制策略,提出了适用于刚性拉索振动主动多模态D-V-I Bang-Bang控制的简化模型;仿真分析表明,主动D-V-I Bang-Bang控制比LQR控制更适合应用于工程实际。

| Abstract: | Oscillation frequency of cables is affected by the bending stiffness under certain conditions.In this paper,the bending stiffness of cable is taken into consideration to establish the active vibration control model for rigid cables.Based on linear quadratic regulator (LQR) control strategy and traditional Bang-Bang single modal control strategy,simplified model of active multi-modal D-V-I Bang-Bang control is given.The simulation proves that active D-V-I Bang-Bang strategy is more suitable for real projects than LQR strategy. |
