The active-passive hybrid electrical circuit with piezoelectric elements was investigated to suppress the vibration of beam. In order to apply passive vibration control and actie vibration control on the beam simultaneously, the concurrent sensing and actuating piezoelectric elements were used. For the passive control, the optimal resistance was used which have the advantage of stable, fail-safe, without power requirement. For active control, the velocity feedback control was used. Based on the hybrid control method, the passive control circuit and the active control circuit can be combined on the same control circuit. Due to the optimal resistance in the hybrid control circuit, the system must have the phase lag. To improve the system performance, a phase-lead compensator was employed. This paper demonstrated theoretically and experimentally that the hybrid control has the advantages of both passive and active control systems.
