A promising method of hybrid vibration control using piezoelectric transducers and switchable circuits is studied. The hybrid approach improves the control performance of the bang-bang active method, by combining it with energy-recycling approach. A part of the electrical energy needed for vibration control is converted from vibration energy and stored, rather than being provided entirely from external sources. In addition, the method recycles the stored electrical energy many times, by preventing it from being dissipated, thus minimizing energy-consumption. We discuss the spillover energy into uncontrolled vibration modes in the hybrid method. A control-chattering prevention is also presented to avoid unnecessary energy-consumption and to obviate residual mode excitation.
