A new method for simple robust control of multimodes of vibration of flexible structures is proposed. Although robust control theories such as H_∞ theory are useful for controlling systems with unknown factors and parameter variations, they are not effective for controlling multimodes of vibration of flexible structures. The proposed method combines the suboptimum control theory and two kinds of filtering technique for reducing the number of sensors and preventing spillover of neglected higher modes of vibration. Therefore, the method is called the filtered suboptimal control method. The effectiveness of the method is demonstrated by showing that the first five modes of vibration of a model structure of large bridge tower are well controlled without spillover of neglected higher modes.
