This study presents an experimental investigation of an active vibration control system implemented on a piezo-beam structure consisting of a cantilever beam with lead zirconium titanate (PZT) patches positioned at the root to measure and control its first bending mode vibration. The employed control method is an adaptive controller that utilizes frequency-domain elements represented as finite series to attenuate periodic disturbances. The magnitudes of the periodic function in the finite series are adapted using PZT sensor measurements, and the resulting adaptive control input is applied to reject periodic disturbances on the beam via actuator PZT bimorph patches. The results of this study provide insight into the efficacy of the proposed adaptive control method in mitigating unwanted vibrations in piezo-beam structures.
