| 摘 要： | 基于Timoshenko梁理论，采用行波控制和独立模态空间混合方法。对悬臂梁的振动主动控制问题进行了研究。采用行波方法实现了对Timoshenko梁结构的振动控制。首先。采用模态控制方法，控制低频振动。而后，采用行波控制方法吸收高频振动能量，实现结构的振动控制。可见，行波／模态混合控制提高了振动控制精度和系统的鲁棒性。本文给出了悬臂梁振动的混合控制策略，最后给出了数值仿真结果。

| Abstract: | Based on the Timoshenko beam theory, a hybrid approach for the active vibration control of a cantilever beam is proposed, which is the combination of both wave and mode approaches for active control. The modal control is applied to suppress vibration at lower frequencies, and then the wave control is designed to absorb vibration energy at higher frequencies. Hybrid wave/mode control improves the accuracy and the robustness of the control system. Hybrid wave/mode active vibration control is described with specific reference to the control of a cantilever beam. At last, numerical simulation is presented and discussed. |
