针对柔性结构振动的每一个控制模态独立进行鲁棒H∞控制设计，同时考虑模态干扰衰减与模态参数扰动的鲁棒性问题，这样有效地抑制了柔性结构的振动，而且对模态参数摄动具有较强的鲁棒性，并以悬臂梁的振动控制为例进行了数值计算，其结果表明这种设计方法的正确性和有效性．

The robust H∞ control design has been developed for each controlled modal vibration of a flexible structure. The modal disturbance attenuation problem and the robustness with respect to modal parameter variation are considered simultaneously. The vibration in a flexible structure is more effectively suppressed, and the active vibration control system designed by this method has a stronger robustness to modal parameter variation. Numerical simulations have been performed by considering the robust control for vibration of a cantilever beam as an example. The simulation results validate the theoretical analyses presented.
