A design method of hybrid piezoelectric damping for flexible structures is proposed in order to achieve the equal vibration suppression performance with less active control power requirement. Values of design parameters of hybrid damping: active control gain, number and location of piezo-elements to be used to passive and active dampings, are designed under equal vibration suppression performance condition. Vibration suppression performance is evaluated by using the gain of the accelerance transfer function of the closed loop system in modal space. Availability of the proposed design method is experimentally demonstrated by using a flexible cantilever beam. The experimental results indicate that hybrid damping is effective comparing with purely active damping from the viewpoint of active control power requirement.
