摘要：

Piezoelectric transducer (PZT) patches may tx attached to structures to reduce vibration. The PZT patches essentially convert vibrational mechanical energy to electrical energy. The electrical energy can be dissipated via an electrical impedance. The authors introduce a method of implementing any arbitrary impedance, using a digital signal processor. The 'synthetic impedance' is demonstrated on a resonant simply supported beam.
