Hybrid wave/mode control of Timoshenko beam vibration

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 mode 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.
