针对施工中桥塔结构的多模态控制问题，提出了一种集总建模方法和基于该方法的简单鲁棒控制设计。该方法是由一个物理状态空间次优控制器，集总模型设计，结合所谓的结构过滤器和软件过滤器，用于防止被忽略的高模式的溢出指定。实验表明，该方法的有效性，显示的前五个振动模式的模型结构的柔性桥塔被很好地控制，而忽略的高模态的溢出。
A lumped modeling method and a simple robust control design based on this method are proposed in this paper for controlling the multiple vibration modes of a bridge tower structure under construction. The method is specified by a physical state-space suboptimal controller, designed upon a lumped model, combined with the so-called structure filters and the software filters for preventing spillover of neglected high modes. Effectiveness of the method is experimentally demonstrated by showing that the first five vibration modes of a model structure of a flexible bridge tower are well controlled without spillover of neglected higher modes.
