| Abstract: | The DSP circuit of synthetic impedance is adopted instead of piezoelectric shunting damping circuit.The principle and implement of the DSP circuit are discussed in detail.Then,a single mode vibration damping with DSP circuit is designed for an experimental cantilever beam,and the result of vibration damping is given.At last,the further study on the development of the multiple mode passive control with DSP circuit is proposed. |
